BIT.TRIP.CORE Soundtrack is the soundtrack to BIT.TRIP CORE, the second game in the BIT.TRIP series. It can be sampled prior to purchase at the developer's Bandcamp page: http://gaijingames.bandcamp.com/album/bit-trip-core-original-soundtrack
Like the other BIT.TRIP games, the soundtrack is a little lesser than it otherwise could have been, because the "melody" of the songs is generated through player actions, and not included in the tracks. That being said, I found these songs to be very nice to listen to, even without the beat noises.
Similar to the other BIT.TRIP soundtracks, half of the tracks are very short - the noises for completing or failing a level, etc, so there's only five "full" tracks on the album. I recommend looking at the price accordingly.
