Funkadelic - Free Your Mind. . . and Your Ass Will Follow [honorable mention]

:-) [5 listens] [Some sources praise this (Allmusic critics and users, Spin guide, Pitchfork) but others pan it (Christgau, Hull, Rolling Stone guide). I could be completist and get it, but that would mean I'd end up getting America Eats Its Young and god knows what else. The undeniable songs are on the compilations.]
