There is no length of a song you can use without risking a copyright claim. Copyright law contains no five-second rule, no ten-second rule, and no thirty-second rule. How much of a song you can use without copyright permission depends on legal doctrines that courts apply after the fact, not on a stopwatch. Every element of a song is protected from the moment it is created, and the two doctrines that might excuse an unlicensed use — de minimis and fair use — are narrower and less predictable than most creators assume.
Why No Number of Seconds Is Safe
The belief that a short clip is automatically legal likely comes from a garbled version of the “de minimis” principle. The phrase is short for a Latin maxim meaning that the law does not concern itself with trifles. In copyright, it means some uses are so tiny and inconsequential that a court will not treat them as infringement. A half-second of music barely audible under dialogue might qualify. There is no fixed line, and federal courts disagree about where any line sits.
The Sixth Circuit ruled in Bridgeport Music, Inc. v. Dimension Films that any unauthorized sampling of a sound recording, however small or unrecognizable, is infringement: get a license or don’t sample. The Ninth Circuit reached the opposite conclusion in VMG Salsoul, LLC v. Ciccone, holding that the de minimis defense applies to sound recordings the same as to other copyrighted works.1Justia Law. VMG Salsoul, LLC v. Ciccone, No. 13-57104 (9th Cir. 2016) The legality of the same short sample can depend on where a suit is filed. If you’re counting on a use being too small to matter, you’re gambling.
Length also matters less than what you took. Courts pay attention to whether you used the “heart” of the work, meaning its most recognizable or distinctive part. A two-second clip of an iconic guitar riff can weigh more heavily against you than thirty seconds of generic instrumental filler.
Fair Use Is a Defense, Not a Rule
The main defense for using copyrighted music without a license is fair use, codified at Section 107 of the Copyright Act.2Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use Fair use permits unlicensed copying for purposes like criticism, commentary, news reporting, teaching, and research. It is not a rule you can apply in advance with certainty. It is a defense you raise once someone accuses you of infringement, and a court decides whether it applies by weighing four factors together.
Purpose and Character of the Use
The first factor asks what you did with the borrowed material and why. Non-commercial and educational uses get more leeway than commercial ones. The central question is whether your use is “transformative,” meaning it serves a genuinely different purpose or adds new meaning rather than simply repackaging the original.3U.S. Copyright Office. U.S. Copyright Office Fair Use Index A music critic playing a clip to illustrate a point about songwriting technique is transformative. Someone laying a popular song over a montage of vacation footage is not.
Two Supreme Court cases set the boundaries. In Campbell v. Acuff-Rose Music, Inc., the Court held that 2 Live Crew’s commercial parody of Roy Orbison’s “Oh, Pretty Woman” could qualify as fair use because parody, by its nature, comments on the original.4Cornell Law Institute. Campbell v. Acuff-Rose Music (92-1292), 510 U.S. 569 (1994) In 2023, the Court narrowed the concept in Andy Warhol Foundation v. Goldsmith, ruling that a work that looks or sounds dramatically different from the source still is not transformative enough if it serves the same basic purpose as the original.5Supreme Court of the United States. Andy Warhol Foundation for Visual Arts, Inc. v. Goldsmith, 598 U.S. 508 (2023) For music, that means adding visual effects or editing tricks will not save a use that ultimately entertains the same audience with the same song.
Nature of the Work
The second factor considers what you borrowed from. Copyright protects creative works more strongly than factual ones, and songs are about as creative as copyrighted material gets. This factor almost always weighs against fair use when music is involved.
Amount and Substantiality
The third factor looks at how much you took, in quantity and quality. This is where the seconds question is most relevant and where it has the least clean answer. Four bars from a deep album cut is different from four bars of the hook everyone recognizes.2Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use
Effect on the Market
The fourth factor asks whether your use harms the copyright holder’s ability to earn from the work, including through licensing. Courts also consider what would happen if uses like yours became widespread, so a video with tiny individual impact can still lose on this factor.
No single factor decides the outcome, and the analysis is highly fact-specific. That is exactly why no lawyer can tell you in advance that a given number of seconds is safe.
What Actually Happens When You Use a Song Without Permission
Most creators who use copyrighted music without a license never see a courtroom. They encounter enforcement through automated systems and takedown notices long before a lawsuit becomes relevant. The legal exposure behind those systems is still real.
YouTube’s Content ID system scans every uploaded video against a database submitted by rights holders. When it finds a match, the rights holder can block the video, run ads on it and take the revenue, or track its viewership, and those choices can vary by country.6Google. How Content ID Works – YouTube Help Content ID regularly catches clips of a few seconds, background music playing from another room, and even hummed melodies. A claim is not a copyright strike, but it can strip monetization and escalate into one if a dispute goes badly.
TikTok’s general music library allows popular songs in personal, non-commercial videos. Content tied to a brand, product, or sponsored campaign is restricted to TikTok’s separate Commercial Music Library.7TikTok. Commercial Music Library – User Terms Using a trending song in a branded post violates the platform’s terms even if you believe the clip is short enough for fair use.
Rights holders can also file a formal takedown notice under Section 512 of the Copyright Act, commonly called the DMCA.8Office of the Law Revision Counsel. 17 U.S. Code 512 – Limitations on Liability Relating to Material Online A valid notice forces the platform to remove the content quickly. Repeat DMCA strikes on most platforms lead to account termination.9U.S. Copyright Office. Section 512 of Title 17 – Resources on Online Service Provider Safe Harbors and Notice-and-Takedown System
If a dispute reaches federal court, exposure jumps. A copyright holder can elect statutory damages instead of proving actual losses. For non-willful infringement, a court can award between $750 and $30,000 per work. Willful infringement — meaning you knew you had no permission and went ahead — pushes the maximum to $150,000 per work.10Office of the Law Revision Counsel. 17 USC 504 – Remedies for Infringement: Damages and Profits An infringer who genuinely had no reason to know can see damages dropped to $200. Courts can also award the winning side its attorney’s fees, which in copyright cases often exceed the damages themselves.11Office of the Law Revision Counsel. 17 U.S. Code 505 – Remedies for Infringement: Costs and Attorney’s Fees
Licensing a Song: Two Copyrights, Two Licenses
Every commercially released song carries two separate copyrights, and this is where creators trying to do the right thing still get tripped up. The musical composition — melody, harmony, and lyrics — is one copyright, typically owned by the songwriter or a music publisher. The sound recording, meaning the specific studio performance you hear on a streaming service, is a separate copyright, usually owned by the record label.
Using a copyrighted song in a video, podcast, or other media project requires permission from both owners. Permission to use the composition alongside visual or other media is called a synchronization (sync) license. Permission to use the actual recording is called a master use license. Skipping either one leaves you exposed to a claim from whichever rights holder you did not contact.12Office of the Law Revision Counsel. 17 U.S. Code 106 – Exclusive Rights in Copyrighted Works
ASCAP and BMI jointly operate a search tool called Songview that identifies songwriters, publishers, and ownership shares for most songs licensed in the United States. The label behind a recording is usually identified on the release itself or on streaming platforms. Neither license has a standard price. Fees are negotiated based on how the music will be used, audience size, and how much of the song you want. For well-known songs, costs can range from a few hundred dollars for a small independent project to six figures for a national commercial.
One workaround: if you re-record the song yourself instead of using the original, you only need a mechanical license for the composition. No master use license is needed because no one else’s recording is involved.
Music You Can Use Without Chasing Permission
Public Domain
A song enters the public domain when its copyright expires. Because a song carries two copyrights, you have to check both. As of January 1, 2026, musical compositions published in 1930 or earlier are in the public domain, their 95-year terms having expired. Sound recordings follow a longer timeline under the Music Modernization Act: only recordings first published in 1925 or earlier are currently in the public domain, after a 100-year term.13Duke University School of Law. Public Domain Day 2026 A 1930 composition is free to perform and re-record, but the original 1930 studio recording of that same song will not be free until 2031. Getting this wrong is a common and expensive mistake.
Creative Commons
Some musicians release work under Creative Commons licenses, which grant permission in advance under specified conditions. Common conditions include Attribution (credit the artist), NonCommercial (no commercial use), and ShareAlike (your derivative must carry the same license).14Creative Commons. About CC Licenses Violating any condition, such as using a NonCommercial track in a sponsored video, revokes your permission and puts you back into infringement territory. Read the specific license on each track.
Royalty-Free and Platform Libraries
Subscription services like Epidemic Sound and Artlist offer large catalogs pre-cleared for use in videos, podcasts, and other projects. License scope varies, so confirm what is included — some cover only YouTube, others include broadcast and advertising — before assuming you are safe across every platform. YouTube’s Audio Library provides free tracks for creators. TikTok’s general sound library allows popular songs in personal videos, while commercial content is restricted to the Commercial Music Library, with some “Premium” tracks carrying additional fees.7TikTok. Commercial Music Library – User Terms For creators who do not want to negotiate licenses themselves, these platform-provided options are the safest route.
