Yesterday, the first Humble Music Bundle launched. It contains five albums by Christopher Tin, They Might Be Giants, Jonathan Coulton of Portal fame, MC Frontalot, and Hitoshi Sakimoto who composed the soundtrack for the Valkyria Chronicles series. If you choose to pay over the average (about 8 dollars at the time of writing) you will also get an album by OK Go. Fun fact: the title image is named hmb1 which implies there will be more Humble Music Bundles to come. Also, if you buy the bundle now some extra stuff will probably be added later on.
