This isn't the first time that the soundtracks from iPhone games have been sold on iTunes, but this is the first compilation of indie iPhone music that I've seen that has been sold as an album. Atomicon's 1337 Mobile Game Music! Volume 1, aside from having some seriously awesome album art, also has some pretty great tracks:
All too often it seems that we just take the background music of these games for granted (or just flat out play with it off), and it's cool to see the musicians of these indie iPhone games getting a little extra recognition. The whole album is available on iTunes for $9.99 or as individual tracks for 99Β’.
