Mod naming error fix

V2 Release:

The music track list was completely revamped! A few tracks stood their ground, but the majority is new.

All tracks are audio-normalized, so they all play at the same volume.

Fixed a few bugs, like custom music not playing in alternative boss fights, Blue Womb is not silent anymore, stuff like that.

Some tracks now make use of Intros.

Changed the music in Burning Basement floor
Changed the music during the fight against The Beast (and made it louder)
Shortened the intro for the secret room music

Ignore this, I screwed up the previous update. This fixes it. :D

Fight against Ultra Greed(ier): The correct music is now playing.

Fight against Hush: Music is now playing. In the previous version there was nothing playing at all.

Cathedral: Changed the music. The old track wasn't blending in well.

First Release! There are already minor changes I am planning. Soundtrack Menu may be implemented at some point, but no guarantee that I'll be able to make it work the way I'd like to.
