Last time I listened to it I somewhat enjoyed Requiem. It probably does belong there though. Beat might be their weakest album, but most of the songs are okay enough to not stand out as outright 'bad', the thing as a whole just underwhelms.
Starless And Bible Black is good. It has some of their best 'proper' songs from that period and even the jams are well done, it's only the title track that doesn't really go anywhere.
You've heard Fracture, right?
