I think the biggest difference is in what drug you're taking while listening to the band. 60s-70s psychedlic bands like Floyd, or the Doors, would be much better left to, gasp, psychedelic hallucinogens, whereas if i've been smoking weed i really like to drive around listening to three six mafia or lil flip. (which is probably a deathworthy sin on these boards haha)
Any kind of crazy psych drug I like to listen to music like Porcupine Tree, Gentle Giant, Emerson Lake & Palmer, Dillinger Escape Plan, PsyOpus, anything that's really hectic and put together bizarrely.
If I'm chilling after a sesh though, I like to put on rap music, MF Doom, Madlib, even DJ Shadow fits the bill, anything that is really well produced comes through awesomely on a good sound system and makes the experience just that much more enjoyable.
