There's a couple out there but Here's a couple I think are the worst.
Billy Squire's The Stroke used In Some New Rap Song,
(The Song was one of his best, and The Rap sample SUCKED Big Time.)
Queen And David Bowie's Under Pressure used By Vanilla Ice
(Ekk!!!, Using a classic on are your debut, not very wise.)
AND OF COURSE THE WORST OF ALL TIME
KASHMIR BY LED ZEPPELIN USED BY PUFF DADDY
What the hell?, Kashmir is Such an Epic song. How the hell do you turn it into a rap song.
Thoughts?
