A lot of the songs you guys are listing (like "Comfortably Numb" and "Riders On The Storm") actually aren't about drugs. I saw a Floyd documentary that said it was literally about when Waters was sick with hepatitis before a tour, and how it reminded him of a trip to the doctor's when he was a kid, or something. And the Doors wrote their song about a killer.
Whoever listed Velvet Underground, w00t! ;)
As for drug music, anything by Gong.
