Shorts & Vertical Video
Original sound
Also called: original audio
Publish a Short with your own audio and YouTube credits it as original sound from your channel, then builds it a page listing every Short that used it. Other creators tap Use this sound and their version links back to yours. You can switch remixing off in the video's settings. Original sound also sidesteps the licensing tangle: no claim to argue about, and nothing that can vanish from the library six months later.
