The Animal Collective bit on the I Dun Get-Em thread got me thinking about bands in which many songs were killer good and the rest deathly awful. Track 2 on Remy Zero's Villa Elaine is killer good and the rest of the album is garbage. Julian Cope albums are like this. Bauhaus, too. Going way back I suppose I could add Led Zeppelin, though their greatness allowed for shit filler tunes.
(Let's avoid bands' who turned to shit on later albums and vice-versa. Otherwise, it'd turn into an I Hate the Gallaghers thread and really who needs that?)
Bands Whose Albums Are Half(+/-)Great and Half Shit!
