So, if u have an album on ur phone that happens to have a song on it, that's not from the album artist or when the album artist is just "various artists", Poweramp thinks that's a reason to sort the album to the artist, that did one song on the album, instead of the album artist. I'll attach screenshots, to show u what I mean. It's obviously a deadmau5 album, but PA decides it isn't. That may look like a aesthetic issue, but it's pretty annoying when u set PA to go to the next list after finishing the one before and u want to listen to all ur songs sorted by album artist that way.
