Murderer: The Notorious B.I.G.

Album: Bad Boy's 10th Anniversary...The Hits
Label: Bad Boy Records
Producer: Easy Mo Bee
Cold Cases: Tracey Lee's "Keep Your Hands High," Puff Daddy's "Victory," Pudgee the Phat Bastard's "Think Big"

This one is a no-brainer. Although it wasn't the most difficult task to outrap Craig Mack, B.I.G.'s verse from the "Flava In Ya Ear" remix remains one of his most memorable of all-time. And he didn't just murder Mack on this single, he basically deaded dude's career. Prior to this release Bad Boy seemed ready to put its weight behind Mack, but afterward it was all Big Poppa all the time. But don't be mad—Biggie contributed enough fire to make this an undeniably classic posse cut, and helped recruit some new talent for UPS in the process.
