To avoid copyright issues on TikTok, Business Accounts need to source promotional and commercial content from the TikTok Commercial Music Library (CML) or from music they have licensed themselves, while personal and creator accounts can pull from the standard in-app library for non-commercial posts. The two account types operate under completely different licensing terms. Using the wrong music source for your account type produces the same enforcement results as using unlicensed music outright: your audio gets muted, your video gets removed, or your account gets flagged.
