Test Subjects!
You may have noticed an update for Light has been published today. This update adds the Light soundtrack to the Light game directory on your computer.
Wherever you installed Light, you'll now find a folder within it called "Soundtrack". This will also apply to anyone who purchases Light from Steam in the future.
Enjoy!
