They're too f*cking old, and only getting older. There will never be a reunion tour, although it's fun to dream. And yeah, all ill feelings between members have been patched up and they played that one-off reunion show a year ago or so.
Animals is definitely one of the best Floyd records and of the famous ones it's one of the least played out by classic rock radio- perhaps because of the song lengths.
You are spot-on. "Sheep" played a major part in getting me into the band to begin with. I was absolutely obsessed with them in 94/95. I remember getting The Wall for Christmas and listening to it all the way through for the first time. It was a musical experience to this day that remains unmatched for me.
During those years I got as many of their albums as I could find and found out about as much of them as possible.
All the songs mentioned as ultimate Floyd "chill out" tunes have been great suggestions. But really, for me, there is one as yet unmentioned that
stands above all the rest and there is no doubt in my mind it is the greatest track Pink Floyd ever laid down. I would go so far to say it may be the best song ever written, and I'd be willing to defend that statement.
That song would be "Echoes."
