1. Rihanna, "Sexuality"
This is just a short, not particularly exciting clip of an unreleased track by Rihanna, but if Prince's lawyers ever hear it, you can probably expect a "controversy." [Autumn Jones]

2. Tunde Adebimpe, "Unknown Legend" (Neil Young cover)
Adebimpe does Scarlett Johanssen one better by singing and acting at the same time, covering this Neil Young track in Rachel Getting Married. [Stereogum]

3. Radiohead, "The Gloaming (DJ Shadow Remix)"
Shadow peppers this Hail to the Thief track with audio of George Bush stuttering his way through two dozen "nuculars." [Pretty Much Amazing]

4. Christina Aguilera, "Keeps Getting Better (Tricky Remix)"
Like Xtina's mood in this new single, the song itself keeps getting better with this new remix by Tricky. [Sheena Beaston]

5. Ludacris feat. T.I., "Wish You Would"
Ludacris displays some ominously sarcastic southern hospitality (and some killer rhymes) on this new track, which appears on his new Biggy Jiggy Mixtape. [Above the Fold]
