If you're looking for something to do this Sunday, try this on for size: The Indie Game Music Bundle. It's essentially the music-centric version of the various indie game bundles that have been ridiculously popular over the last couple years. Like those bundles, all of this music is DRM free, and you can name the price you want to pay. In addition, a portion of the proceeds are going to the American Cancer Society and Penny Arcade's Child's Play charity.
For as little as $1.00, you can get your hands on the soundtracks from Aquaria [$4.99], Sword & Sworcery [$4.99], Machinarium [$4.99] and two non-iOS games, Jamestown and To The Moon. If you contribute $10.00 or more (so, basically the cost of one of these albums normally) you get ten additional game soundtracks, with more bonus soundtracks potentially coming as more sales are made. Oh, and for $10.00+ contributions you also have the option of downloading the music in lossless FLAC.
This whole deal is pretty awesome, as not only are you getting some of the best indie game music the App Store has to offer, but you're also potentially getting tons of bonus stuff and donating to two great charities in the process. It's worth it alone for just the Sword & Sworcery album, but the rest of the music is great as well. So, seriously, head over to the Indie Game Music Bundle site if you're at all interested. This deal is only going on for four more days, so don't wait too long if you are.
Also, in a similar music-related PSA, if you like the Sworcery soundtrack, Jim Guthrie actually has a new album available which you can either download digitally or preorder it in vinyl. Additionally, if you're really retro-oriented, the Sword & Sworcery soundtrack is also available on cassette if that's your cup of tea. Or, if you're a Spotify person like me, this whole album can be streamed to your heart's content.
