Echoes, Atom Heart Mother Suite, Shine On, Sheep, Dogs... those would be most of my favorites, I'm into epic pieces. The live versions of Saucerful of Secrets and Careful with that Axe, Eugene are pretty awesome, as is the live version of Granchester Meadows. Breathe, though one of their simplests and shortest pieces, is really amazing, too.
Welcome to the Machine Money Time Wish You Were Here these are some of the top songs i can relate to the most in life.
i love Set the Controls from Live At Pompeii i prefer their earlier stuff, but after Syd left, when they were still psychedelic not yet progressive rock but i do like some of their stuff from Wish You Were Here and The Wall
Other. its hard to choose just one but Astronomy Domine or Interstellar Overdrive or Echoes or... i could keep going and going. cant choose
Definitely 'Comfortably Numb'. Also both parts of 'Shine On You Cray Diamond'. 'Dogs' 'Echoes' 'Wish You Were Here' 'Sheep' 'High Hopes' 'Us And Them' 'Run Like Hell' 'Time' 'Pigs (Three Different Ones)' 'Hey You' 'Sorrow' (live)
i think the question would be what's the best album? I cant pick one song!!!!!!!!! anything off of 'Animals' or 'Meddle'
