No, the music overlay music offered in the app is licensed and can be added. Creators who are performing covers, I believe, generally have the license held by TikTok or have their videos muted/taken offline. Special arrangements are made for intentional or encouraged content . That is a guess, but things like Megan Trainor’s “Gucci” where she is both the original artist and a participant would be a case like this. I would think Grace Kelly and sing alongs on arrangement-bound copyright material like Pentatonix doing public domain carols (or even Roger’s and Hammerstein) are negotiated licensing if outside of their pre-negotiated license.
That seems like a lot of work. It would be easier for me to write a bot that will post every article from my favorite sites to technology@lemmy.world. Then I could have another bot summarize it in the body.
Oh, wait…several people already have. :-/
