The Sparks remix of Morrissey's 'Suedehead' is a must! I found it via I-Tunes, but for your traditional types you can get it on the album "Future Retro."
It's a great piece because I think it exposes the relationship (artistically speaking) between the two artists. Ron and Russell Mael tear into the song as if they were Picasso tearing into an image in front of his canvas. Get it!
