it's like the humble indie bundle, but just VGM. no games themselves.http://www.gamemusicbundle.com/
Relevant to RPGFan's interests, To The Moon OST is there. That alone is worth the $1 minimum. And the Jamestown OST? *chills* so good!
Should you pick the $10+ route, that bonus music is amazing. If you haven't heard the Shatter OST, or Tower of Heaven ... sheesh. You're in for a treat.
