Character Select - Sonic Catalyst OST

"Basic as heck", in the words of Lemoner.

Used for the Extras portion of the main menu.

The song for the first zone, Tropic Tranquil.

The song for the 3rd zone, Aqautic Chamber. 

It's almost as if this metropolis is frosted....hm....

The song made for the final zone of the game, Robo Refuge.....get out there and stop Dr Eggman!

there seems to be some sort of krypto in these underfalls
