I hope this is the right place for this: I uploaded a video of myself playing along with Adele's "Hello" with a really cool octave-bass solo, and it got dinged for a copyright claim, and has been blocked. I have asked for an appeal, but I see tons of play-along videos up there. Why was mine different? How does one get around that? Just curious for the future. I make and post videos for some of my students, and would rather not get dinged like that again! Any advice?
