For those not familiar with Groupees, it has several bundles per week, sometimes games only, sometimes music only (especially music that may be of interest to gamers), and sometimes a combination.
$1 tier: RH Soundtracks - Collection 1 & 2
Chill Carrier - Back In The Days
Chris Collins - Meditation/Yoga Music Bundle
Chris Collins Exclusive Track
FreePD Special Collection

If they sell a few more bundles, an additional soundtrack will become available. The music is downloadable in mp3 or FLAC format. Mp3s are for losers. Go FLAC.
