Opening seconds

Paradise by the Dashboard Light - Meatloaf

crazy train by ozzy. the song is not as good as the opening though.

i like the way the beastie boy's "check your head" starts with a sample of cheap trick saying "this next one's the first song on our new album."

i also love marilyn manson doing the boat song from willy wonka at the beginning of "portrait..."

beyond those,

government flu, by dead kennedys
suicide's an alternative/you'd be sorry, by suicidal tendencies
somewhere out there? part 1, by orbital
holidays in the sun, by sex pistols
face up, by new order

i could go on, but won't.

shine on you crazy diamond - the floyd... just cos it goes on for days
bittersweet symphony - verve - puts prickles down my back
whats goin on - marvin gaye
bottle rocket - go! team

good subject for a thread though - got me thinking - tis is by no means a definitive list

You realize that that bit of strings there is a sample, right?
