And then L4D1 support came in, now with its own distinct but energetic track! L4D2 variant unchanged.

By random request, here is an update that either does nothing at all, or makes the theme very audible for players!
Yeah, did a little fiddling with Audacity and decided to have two duplicates of the theme play simultaneously and exported so that they were merged to the two-audio channel standard L4D2 mods need to function. Did a little testing, and I think it's definitely enough of a difference to make someone's day. Heck, maybe thrice may be needed, but at that point the audio seems to become fizzy, so double it is for now!
