The last, and current, indie game and music bundle with just over 17 hours left to purchase is in my opinion the best bundle of the bunch.
For whatever price you want to set you can get Miner Wars and Aztaka, which both look like interesting and fun games. Additionally, you get songs from both The Balconies and Clothes Make The Man, as well as the OST of both games.
Miner Wars from what I have heard is a kind of open world third person shooter. You fight in a large asteroid field and can destroy and punch holes in anything you see.
Aztaka is 2D action RPG, which I have seen a few times but do not really know much about.
