I'm considering uploading a cover I did of a Halsey song, but I'm confused about how the "covering" rule works here.
I had a Blitzkrieg Bop cover removed some years ago because it broke that rule, but there are covers of video game and film soundtracks, which is what confuses me. I've also seen covers of songs like Derezzed and Hey Ya which have over thousands of views and were never removed.
Where exactly is the line drawn? Is it when the cover directly samples part of the original song, or is it something else?
