1. Nelly, "Bay"
Nelly follows generations of pioneers (or E-40, anyway), making the arduous journey from St. Louis to San Francisco (or Oakland, at least) in this tribute to the Bay Area. It's getting hot in herre, but it's a dry heat. [Cocaine Blunts]

2. J Dilla, "Trucks"
On this previously unreleased track, Dilla takes Gary Numan's "Cars" — a spooky social critique of the isolation of technology and consumerism — and uses it for the basis of "Trucks," a song about how awesome trucks are. [Nialler9]

3. Britney Spears, "Something More"
An unreleased Britney track has surfaced, and as nobody's sure whether it's a new song or just an outtake, we can be certain of only one thing: It's terrible. [Pretty Much Amazing]

4. DJ Shadow, "San Francisco"
Nokia asked DJ Shadow to help launch a contest which asks people to record a song with the sounds that define their city. Shadow's approach is to basically use the whole city as a turntable, Lauryn Hill style. It's got trolley bells and harbor fog horns, and, if you listen carefully, you can hear Web 2.0 applications being overvalued. [So Much Silence]

5. Nine Inch Nails, "Echoplex"
Trent says thanks to fans with this second single from his free new album. Well worth the money you won't be spending to get it. [ Deaf Indie Elephants]
