Once your release is live on TikTok, creators all around the world will be able to use it in their videos. Artists are paid for the amount of times their work is used in a new TikTok video, not for each stream of a video.
TikTok allows you to express your creativity without limits. You can use many effects and features to come up with cool lip sync videos, ask for feedback with the Duets feature or anything else you can think of.
