Too much slating of Wish You Were Here.
The Album is basically 4 tracks right, Shine on You Crazy Diamond, Wish You Were Here, Have a Cigar and Welcome to the Machine.
The former being the two best tracks (imo) Pink Floyd ever made.
Admittedly the other two are not on par, although I still don't mind either. But as an album you are basically getting 50% of the best work they ever did.
Dark Side of the Moon as an album in it's entirety is better, sure.
Animals is pretty good, but I do feel some of those go on a little though.
The Wall also has some really good tracks, both parts of In the Flesh, Comfortably Numb, but Young Lust and Run Like Hell both good also. There are some other really good tracks on that album, I quite like some of the Waters influenced ones. But as an album as a whole, some of the tracks are not great.
I don't think any of the earlier stuff or later stuff was quite as good, I didn't like the really early Sid Barret stuff, in my opinion sounded like a slightly proggy version of The Beatles, and neither Gilmore nor Waters produced anything great after they parted ways with the exception of the odd one (Gunners Dream wasn't bad, Learning to Fly etc).
If you want a good slightly under rated Floyd track listen to What Do You Want From Me, or On The Turning Away.
