I wrote my response to the Blur part without seeing that you basically wrote the exactly the same thing.
Most people are going to pin down the Dave Floyd albums as Floyd's worst. I don't like anything off of those albums as much as "Green is The Colour" or "Cymbaline."
Was there a general agreement that ATTW3 is Genesis' worst? I'm going with Calling All Stations obviously but if it weren't that it'd be Invisible Touch--their biggest hit! Of course, let's not forget how few people have probably still ever bothered to hear From Genesis To Revelation.
