it sounds great holy shit u crazy person u. thats the first cover of a song ive made so its honestly surreal hearing it.
as for credits in the audio project there's a "Users & Credits" tab at the bottom, and in that tab there's an "Audio Credits" section. u can just link the song in that section. i also updated the cover art and title a bit, just in case u wanna match your cover and the original with each other :-)
