Radiohead has turned into that at times (i.e. certain albums, or certain tracks on certain albums). They certainly didn't start that way, and they still write very memorable and interesting songs, I think - when they want to. Wilco has always been a songs band to me; even when Tweedy wants to stretch out and do his krautrock/post-rock thing, you can feel the call of traditional songwriting pulling him back in.
