I have it on record. Belive me, it's almost worn out, now. my fav on it would be "If" or "Summer '69". This record was the beginning of Floyd's new sound that they would carry out on other awesome albums like Meddle and Darkside.
It is great to listen to while high also, especially Alan's Psychedelic Breakfast. It just sounds so cool. If you like it, I'd advise listening to Meddle if you already haven't. Also pick up their 60s stuff like Piper at the Gates of Dawn and Saucerful of Secerets. Those are also great.
