Heads up, music aficionados: the second volume of the Portal 2 soundtrack ("Music to Test To") is now available for download. Don't reach for your wallet… it's free!
The 18-track volume features such hits as "Robot Ghost Story," "Bring Your Daughter to Work Day," and "I AM NOT A MORON." Ring tones have also been made available for all of the tracks, suitable for both Android devices and iPhones. (MIDI files for your old java-based flip phones are not available upon request.)
The first volume, which contains 22 tracks, is still available for downloading. And there's a third volume on the way… because Portal 2 has a lot of damned music in it. Awesome music.
