As for the Floyd: I probably have to give Animals a proper relisten. It was my least favorite core (Meddle to Wall) album of theirs so I'd probably find it refreshing now. I *did* really enjoy The Wall once, and not because I identified with its mopeiness and self-pity rather than it was the concept album of concept albums, and that was really cool and they made a movie out of it zomg. I even liked "The Trial". When I got into the album I was familiar only with Jeff Wayne's War of the Worlds (would belong on this list in its own right) and this one blew it out of the water -- *and* it had that "we don't need no education" song.
With the rest of classic Floyd I guess it's mostly due to overplay. I respun Dark Side a few years ago and I guess it mostly holds up and would reward a relisten every now and again. Meddle and Wish You Were Here were a different story. There's about a side's worth of really good music on the former but I couldn't take ten minutes of the latter (the "Shine On"s are tedious, and what do I have to look forward to after that? "Welcome to the Machine" is awful, "Have a Cigar" is no great shakes, and the title track is great, I guess.)
I think everyone agrees about "Comfortably Numb" being the best on The Wall. I've heard some Dream Theater song rip it off (Beeds, Ken?) and I'm not going to look around for Queensreich's "Silent Lucidity" -- I don't remember whether that ripped off "Numb" or just Floyd genetally.
They played mother####ing "Mother" on the radio once.
