Hey guys!  I just purchased the Soundtrack DLC last night and I don't seem to be hearing anything new.  All I keep hearing is the same (original) soundtrack.  I've confirmed my files via Steam, checked the cache and verified the files etc.  It's been downloaded alright but I still don't hear anything new.  I've checked the options and there doesn't seem to be anything there to let me know what track is playing or even a way to switch tracks... I don't see anything that suggests that I have new tracks!  Am I missing something?  Is there something else I should be doing to get the new sounds to work?
