I would except Wish You Where Here from my earlier comments--it's rock solid. There's something human there. Probably Dave Gilmour. The problem with Roger Waters is that he's so damned predictable! What's the point of The Wall except to say that the "big star" has gotten to the point that he despises his stadium audiences and wants to spit in their faces. It's a catalog of his own dehumanization, I guess. I just find no will or desire in Rodg to rehumanize himself. No redemption song. Just condemnation of the stupid nazi-ish fans, War in general, Mrs. Thatcher. I mean, look at the magnum opus The Final Cut--written about the Falklands War! I mean, c'mon, Roger! I'm surprised he didn't do follow up on the Grenada invasion. That's why I'll have to give Gilmour credit for "Momentary Lapse of Reason"--he's edging out of fingerpointing self-absorption PF territory to something positive and humane in songs like "The Turning Away" and "Learning to Fly" even if the productions does sound a little too much like '80s Genesis.
I think Syd's got a phenomenal voice--totally unique. Who else could sing "Terrapin"? And the last lines from "Jugband Blues" or the line "Wouldn't you miss me at all" (in Dark Globe)--that's about as inside a lyric as you can get. We ain't talking pitch here--this guy's singing open, revelatory in a way that the Beatles do at their best (Lennon usually in his self-revelatory moments) or in the way Billie Holiday could inhabit a song.
Don't mean to rant--it'll always be a battle in popular music. Syd or Pink Floyd, nakedness or contrivance.
