Here's a couple of my favorite Stevie Wonder edits/remixes. It's hard to rework on such classics without raping them but these guys have really done it right. It takes a lot of skills and love for music to get it right.
Stevie Wonder - Superstition (Todd Terje Edit) [320 kbps, zShare]
Todd Terje is a master of re-edits. He seems to be able to take any classic tune, rework on it heavily and still make it work.
Stevie Wonder - Uptight (B.Cause Fraze Ruff Ride Refix) [320 kbps, zShare]
DJ B.Cause, one of my favorite DJ's around, has done an excellent uptempo remix of Uptight that's heavy on the bass.
Stevie Wonder - All I Do (U-Tern Disco Edit) [320 kbps, zShare]
This one's amazing. A solid disco/boogie version by DJ U-Tern. It has a nice and long intro and outro making it dj friendly.
