when im stoned, and listen to pink floyd i seem to think more on the lyrics and get very hung up on them, to the point that it even influences me from a thought i had while stoned - once im not stoned, i still act on that thought. I think the song 'time' comes to mind, i overthinked that one and it got me a little sad. Breathe is one that i overthink on.

As for the music while stoned, it speaks for itself. shine on you crazy diamond while stoned is a must for all stoners.

i find the album 'meddle' is a good sleeping album, i.e. it makes me drowsy and go to sleep (yet its still an awesome album).

All in all, pink floyd + weed = goodness.
but pink floyd by itself is great too. Just with that added weed it makes you think the lyrics more i guess, and appreciate the musics a bit more too. sometimes. unless your too stoned and all you want to do is eat burger kings.
