Oh my god someone needs to rip the Battle mode BGM of the beach area

This music makes me think of either Waverace or Ridge Racer. Take your pick.

I also find that I think of sonic adventure 1 constantly, between the music and the actual map itself. Then the buildings off in the distance have a neat PSO1 mystery element to them.

I've always enjoyed the music that comes from sonic team.

im not 100% sure but i think there are 2 bech battle themes one for normal and one for darker. i want he darker one.

If there's different battle themes, the different one could be for emergency codes, maybe?
(I haven't played enough of the new area to know though, only played it a little bit, since I've been focusing on my new character)

On the topic of the music, it's worth mentioning that there are more two versions of all the battle themes, which is partly why the music is so modular. Some I've noticed, are emergency trials, lots of enemies, and enemies spawned but not engaged in combat (I think... it tends to happen when I run past a bunch of spawns without fighting in TAs). According, to Sega there are also versions for when you're doing well, and for when things are grim. I know that in the skylands the "you're doing good" section is part of the main theme but it's hard to pinpoint the others. I wouldn't be surprised if there are different versions for Darkers too and I just didn't notice.

EDIT: Oh and PSE Bursts, but we all knew that. XD

MOAR EDIT: I just remembered. Weather might affect it too, though the weather itself seems to be affected by ingame factors as well, so I'm not sure how that works.

Things like this are why I like Ruins as well. These two areas have a very classic feel to them.
