1. G-Unit, "Grimey" In this new track from the upcoming G-Unit album, 50 Cent confesses to being dirty, grimy, and filthy, but stops short of being honest about his acting ability. [Nah Right]

2. R.E.M., "Supernatural Superserious" (live on The Colbert Report)
Stephen Colbert's first-ever musical guests "bona fide rock band" guests turn in a serviceable version of their new single, which doesn't help us like their new album any better, but isn't bad anyway. [Stereogum]

3. Madonna, "4 Minutes to Save the World" (Junkie XL Dirty Dub Mix)
While this remix fails to save Madonna's crappy new single, it's an improvement, at least. [Get Weird Turn Pro]

4. Lupe Fiasco, "Superstar" (Acoustic version)
Sure, this may be the third version of "Superstar" we've featured in Right-Click, but it's the only one that sounds like Dave Matthews had a hand in. [Nah Right]

5. Radiohead, "Nude" (RAC remix)
If there has to be a winner in this silly Radiohead remix contest, we sort of hope it's this one. [I Guess I'm Floating]
