This is a pay what you want bundle. Part of the donations go to charity (American Cancer Society or Child's Play) and there are several albums included. The main five are:

Aquaria, by Alec Holowka
To the Moon, by Kan R. Gao
Machinarium, by Floex
Jamestown, by Francisco Cerda
Sword & Sworcery, by Jim Guthrie

And if you pay $10 you get FLACs and the following:

8-Bit Pimp, by A_Rival
Mighty Switch Force, by Virt
Shatter, by Module
Cat Astro Phi, & Passcode by Disasterpeace
Machinarium Bonus EP by Tomas Dvorak
Tower of Heaven by Flashygoodness
Eternal Daughter by David Saulesco
Songs for the Cure 2010 by Various Artists

And there seems to be an unlock once 10,000 sales are reached. The top three contributors will get additional goodies, too.

Just thought you guys should know. I plan on getting these today.
