This is a fun one! A few of my favorites:
Format = Song (original artist) - New version: Why
Like a Prayer (Madonna) - H2O: Faster tempo and fun "punk" version of a classic everyone knows
Sunshine of Your Love (Cream) - Earth Crisis: Downtuned, straight ahead hardcore version of a killer riff
No Ordinary Love (Sade) - Deftones: Chino's vocals on this are haunting and perfect for the song
Hurt (Nine Inch Nails) - Johnny Cash: Between the video and Cash's vocals, it was like this song was written for him
Cats and Dogs (Gorilla Biscuits) - H2O: While hard to improve on the original (vegetarian/vegan classic!) the H2O version improves on the riff and has more energy.
Ghost of Tom Joad (Springsteen) - Rage Against the Machine: Great arrangement and Zach's vocals/energy put this song over the top.
Oh yes, Johnny Cash "Hurt",and Cash doing Soundgarden's "Rusty Cage"", too.
