As much as a film like No Country for Old Men can impress with the barren sounds of music-free silence, many films thrive on the careful selection of songs -- sometimes catapulting a movie to even bigger fame. Garden State. Pulp Fiction. What would either be without the music that energized each scene and made many moviegoers run to their local music store? Sometimes the collections are lesser-known but still impressive, like the '90s beats of Hal Hartley's Amateur, or the electronic and retro melodies of Gregg Araki's Splendor.

Columbia Records has issued a press release stating that SXSW will not only host the release of the high stakes Vegas flick 21, but also the film's soundtrack. 21 is the film based on those M.I.T. students who broke Vegas with their brainy ways, and it stars Jim Sturgess, Kevin Spacey, and Kate Bosworth. The feature is based on the book Bringing Down the House, and while I wish I could say that there would be a wacky, re-named cover of "Burning Down the House" on the upcoming CD, there is not.

However, the soundtrack is looking like a pretty interesting set of tunes, headlined by a cover of The Rolling Stones' "You Can't Always Get What You Want," performed by the Belgian alt-rock band Soulwax. But it's certainly not a collection of all like-minded tunes. There's some R&B with Rihanna, Amon Tobin's funky "Always," and a tune from The Aliens -- which includes 2 guys from The Beta Band.
