I've been listening to the music on the teaser site for awhile now, and the best tracks, imo, are the following-
1. Lava Passion (Final)
2. New Beginnings
3. Water in the Dancefloor
4. Frozen Lavareef (Is it just me or does that sound like Perfect Dark Zero?)
5. A tie between Doomsday and Icecap 4 Life, I can't decide, between the two, which one I think is better.
