I feel like I should have known that. But awesome, thanks!
Not all or even most, but a significant amount of the album art that downloads for a song is either: 1) the back cover 2) a snapshot of the band 3) another band's album cover 4) random picture I'd love to be able to reject this art and individual basis and have the system attempt to find more relevant album cover. Imo, that'd make Poweramp perfect. Just my .02
