Valve Releasing Portal 2 Soundtrack for Free

Valve is releasing its much-demanded soundtrack for Portal 2 for free on the game's official website. 

The soundtrack, titled Song To Test By, will be released in three volumes. The first volume, which contains 22 tracks, is currently available for download.

With Aperture-brand turrets, boots, bots and panels flooding the applied science aisle of your local department store, you could forgive the up-and-coming test lab for taking a breather. Judging from their latest press release, though, their laurels remain untouched by backsides. Bolstered by recent breakthroughs in the field of jazz smoothing, Aperture announced today the first of three downloadable aural stimulus packages.

Whether you're a mega-science corporation with decades of test experience, or a young start-up liberating your first test subject from non-testing with a chloroform-soaked rag, Aperture guarantees results. Wake up your test subject, open the chamber door, and press play–let Aperture's patent-pending rhythmic compliance enhancers do the rest.

The download is available for everyone.
