spirit of the radio - rush, is a pretty ****ing cool one to learn, 'tis groovy as **** and fun to play
anything by victor wooten, mind you if you can get through more than 60 seconds of any of his songs and keep u when he goes off on one your a better bassist than i am. - (classical thump, me and my bass guitar, you can't hold no groove ect...)
my generation - the who, but if your looking to be kick ass for the first verse play 2 notes for every 1 note he plays.
anything off the killers album - iron maiden, steve harris' bass rocked and wasn't that hard to learn.
