The general library is licensed for personal, non-commercial posts. The Commercial Music Library is a separate catalog cleared for brands. Almost every unlicensed brand use of popular music happens in the gap between the two.
The general library: built for personal posts
The general library is the catalog most people picture when they think of TikTok music: chart hits, major-label releases, viral sounds and trending audio. Platforms access it through blanket agreements with labels and publishers, so personal accounts can use it at no individual cost.
Those agreements cover personal entertainment, not marketing. TikTok's own music terms say general sounds shouldn't be used to promote, advertise or sponsor a brand or business unless the user has secured the necessary rights themselves. Put simply, the license covers someone posting about their weekend, not a company selling a product.
The Commercial Music Library: built for brands
The Commercial Music Library (CML) is TikTok's separate catalog of tracks pre-cleared for business use. It holds roughly one million tracks, is free for business accounts, and covers organic brand posts, ads and branded content on TikTok.
It has two big limits. First, most mainstream chart music and major-label releases aren't in it, which is why brands often find it weaker than the personal library. Second, the clearance stops at TikTok: CML terms only allow videos with commercial sounds to be posted within TikTok, so the same video reposted to Instagram or YouTube isn't covered.
TikTok also enforces the split in the app. Business accounts see only commercial sounds when they add audio, and general-library music doesn't appear for them.
Side by side
| General library | Commercial Music Library | |
|---|---|---|
| Who it's for | Personal accounts | Business accounts |
| Permitted use | Personal, non-commercial content | Commercial content: organic brand posts, ads, branded content |
| Catalog | Millions of tracks, including chart hits and trending sounds | Around 1 million pre-cleared tracks, mostly not mainstream releases |
Where the line gets blurred
The rule is clear on paper. In practice, brand content regularly ends up using general-library music. The most common routes are:
Posting from a personal account
A brand runs a personal or creator profile to unlock the full catalog. The test is the content's purpose, not the account type, so a promotional post is still commercial use.
Creator and influencer partnerships
Sponsored posts go out from the creator's personal account, set to a trending song. The creator has access to the track, but the content is advertising.
Cross-posting
A video made with a CML track is downloaded and reposted to Instagram, YouTube or a website, where the TikTok clearance doesn't apply.
Uploading audio directly
A team adds a commercial track to a video in an editing app before posting, bypassing the in-app library entirely.
Lapsed or limited licenses
A brand licensed a track for one campaign, territory or period, and the content stays up after the deal ends.
Most of these aren't deliberate. Many marketers assume that if a song is available in the app, it's fine to use. That assumption is the single biggest source of unlicensed brand use on social media.
What it means for rightsholders
If your music sits in the general library, it is available to millions of people for personal posts, which is good for discovery. But that availability doesn't extend to brands, and when a business uses your track to sell something, it typically needs a separate sync license from you.
That makes the gap between the two libraries a licensing opportunity, not just a compliance issue. Knowing where brands use your catalog, and whether a license is in place, lets you turn accidental misuse into proper licensing deals.
The takeaway
The general library is for people. The Commercial Music Library is for brands. When brand content uses general-library music, that use generally isn't covered, and the rightsholder is the one left out.
