Robert of The Radish has an excellent playlist of songs produced by Rick Rubin.

Rick got Johnny Cash the respect he deserved and he should be worshiped for this alone. However, he's also given us timeless albums by groups as diverse as Run-DMC, The Cult, Neil Diamond, Red Hot Chili Peppers, Public Enemy, The Mars Volta, Paloalto, Tom Petty, Slayer, Jay-Z, System Of A Down, The Beastie Boys and Nine Inch Nails. Enough said. Enjoy.
