regular weed it don't really do nothin for your thoughts and shit but when I smoke some of that head banger boogie shit some of that Hawaiin shit I be writin super crazy ill bombs super crazy ill bombs super crazy bombs
Aerosmith "Dream On" - Eminem "Sing For The Moment"
Enya "Bodicea" - The Fugees "Ready Or Not"
Daft Punk "Harder, Better, Faster, Stronger" - Kanye West "Stronger" (Kanye's lyrics are weak as fuck - weakest on the album - but the sample+beat is fuckin slammin)
maybe my favorite sample used ever: Crowded House "Don't Dream, It's Over" - Classified "It Ain't Over"
Here is another GREAT one, unfortunately the Marley sample was removed when UGK's first record came out on JIVE, obvious violation of copyright and such:
JIVE did this with a ton of their artists, took their demo or underground tracks and "cleaned" them up lyrics / sample-wise, completely fucking a lot of albums up in the process
Here is another winner in the copyright violator category:
Ghostface The Soul Controller; samples "A Change Is Gonna Come" by Sam Cooke & dialogue excerpts from the films Carlito's Way & The Usual Suspects
This one is only available on the early presses, too bad cause it's fire
