My favorite thing to listen to when I'm stoned is NIRVANA, but Pink Floyd is GREAT band to listen to. There are A LOT bands that I like to listen to and it probably would take me a couple of hours to list but my all time favorite has to be NIRVANA.
I haven't listened to Jefferson Airplane since high school!
Beatles/Jack Johnson/Marley are great for just chilling out.
When I want to go for a "productive" hyper high I like to listen to electronica -- mostly drum and bass, goa-psy trance and techno. (www.di.fm is good for free streaming)
Pendulum - Sounds of Life:
Listen to just about everything. Jedi Mind Tricks, Twista, AZ, and Lupe Fiasco mainly when I feel like cwalking.
Lots of West Coast Rock/Alternative and local bands while I'm driving (local radio station).
Zepplin and Tool when I'm fucked out of my mind.
Pain, Seether, Sum41, Bush, Muse, Maximum the hormone -- great music for competitive gaming session.
The Jet Set Radio soundtrack is amazing.
Marisa: she stole the precious thing.
And yes, I do listen to Jpop from anime (Darker than Black ending is AWESOME) some J Ska recently too, band called ムラマサ☆ (Muramasa).
Anime music is a given.
