Why?

Why are so many bands releasing b-sides albums after only having released one or two albums? Why release a b-sides album at all? Why not do what bands like Radiohead and Bloc Party do and release multiple singles or e.p.'s with b-sides? It's something that can satisfy you're appetite for stuff by the band. When a band releases a b-sides album, you take it as an album most of the time and it's really disappointing cause the songs are all from different recording sessions and there is no cohesion.
