Almost impossible to answer, but I'll have to narrow it down to my top 5: (in no particular order)

Fearless
Echoes
Is There Anybody Out There
Dogs
Shine On You Crazy Diamond Pt. 1

Honorable Mentions: All their other songs.

Echoes, hands down.

Honourable mentions to Julia Dream and Set the Controls to the Heart of the Sun

Tough call. Favourite albums Wish You Were Here, Meddle, Animals, Relics. Favourite track maybe See Emily Play. Been many years since I listened to their albums though so this is probably more a sentimental favourite than based on musical merit.

On further reflection I like many of the tracks from Relics. The Nile Song was probably one of the first I got into. Pink Floyd was the first band I obsessed over. Had all their albums on vinyl when I was a kid (well teen I guess 12-15). Kind of lost me with Final Cut though.

Geez this is hard. I'd say probably either Time or Dogs, perhaps Hey You. There's more I could list but honestly it's so difficult! I also have a fetish for Jugband Blues as well... :thumb:

My favorite is time. But the Animals album...if you listen to that in chronological order...its just unbelievable!

btw. I read somewhere, and loved this quote.
"Being high doesn't make Pink Floyd better, Pink Floyd makes being high better!" :D

As cliche' as it sounds, my favorite is, and will always be, "Speak To Me (Breathe)" From Dark Side Of The Moon.

Echoes, Time, Comfortably Numb, and On the Turning Away
