The reason for this question became apparent when I wanted to contribute the song “Powerline - I2I (nanobii’s Live Edit)”, a live bootleg on SoundCloud (link). I considered the song to be a remix, considering it’s called an edit and it’s in my opinion “A substantially altered version of [the] song” (From: Terminology).
I have been told that remixes, when officially released, should credit the original artist. This might be a bootleg but still, I think the song should therefore be credited to Powerline, the fictitious artist from the 1994 movie “A goofy movie”.
And if that is correct, should the original recordings (for example, “Stand Out”, link) also be credited to Powerline (and then also to the other fictitious character, Treeny)? If so I feel like this would be a snowball of changes. But if it’s necessary then it is what it is. I wonder what the community thinks of this problem.
