Not sure what you're saying here — that you think no Pink Floyd song sounds like the Grateful Dead song Touch of Grey? Or... are you saying the difference between Pink Floyd in the 1960s/1970s is not so different to Pink Floyd in the 1980s as Grateful Dead, Fleetwood Mac, and Moody Blues were from their latter work?

Because I can see it either way, but I don't like Pink Floyd that much. I like some of their songs. I like the stuff on A Momentary Lapse of Reason — I feel like it's a more mature sound. I also like that song off Ummagumma (I think) with the really long title. Something like "Several Species of Small Furry Animals Gathered in a Cave and Grooving with a Pict." Pretty sure that's mostly it, without Googling it. Dark Side of the Moon is okay, but I feel it's a bit overrated. Some clever word play. Annoying alarm clocks in Time. Maybe it's better if you're high? I don't get high. And The Wall, also overrated, but I did like some of those songs as well. So, I like some of their songs, and I like some quite a bit. I listened to a more recent album from them, which was all/mostly instrumental, and that was cool, but I didn't listen to it again. I guess I like them more than a lot of people but wouldn't call myself a fan.
