The first thing to realize is that there are 4 main phases of Pink Floyd, and can be considered different bands: 1) the Syd Barrett era. They were a psychedelic pop / experimental band, led by charismatic singer / songwriter / guitarist Syd Barrett. They had 1 album (Piper at the Gates of Dawn), and several singles. I like this era a lot. Try listening to Arnold Layne, Lucifer Sam, See Emily Play... 2) Middle period - after Syd went nuts, they brought in Dave Gilmour to replace him. Everyone tried their hand at writing songs, and it took some time to get their footing. This is a more introspective, laid back period, and when they did those sound track albums people are talking about. They were in the top 40, but not really stars yet. The culmination of this era was the movie Live at Pompeii. 3) Roger Waters era - bass player Waters wrote an entire album of songs about madness and alienation, this was Dark Side of the Moon, their most popular album, which propelled Pink Floyd to the top of the charts. Waters had developed into a genius song writer, but with each successive album, became more domineering and difficult to work with. These albums tended to be ambitious concept albums, dark and disturbing, in contrast to the laid back vibe of the previous era. The last 2 Waters albums, The Wall and Final Cut were essentially Waters solo albums, and at the end, half the band had departed. 3) Dave Gilmour era - Waters went solo, and expected the band to end, but Gilmour decided to bring back the 2 ousted members of the band, and continue as Pink Floyd. This period isn't very interesting IMO. So my personal tastes: I find The Wall and most of the Waters-era albums kind of overpowering and negative. I prefer the Barrett stuff, as well as Live at Pompeii. YMMV...
