So, we put down cover artists, and the actual artist in the same song for a covered song, and if a solo artist was in a band in the game, then for the band credited, we put it under the band category, and if it only credits the solo artist, then we put it in as the artist in his/her new category, and if there is more than one song by an artist, then we make a category for them/him/her.

So, if those are the rules for the categories, then I'm sure about it.
