All I can find is the .ogg files, I need access to the stereo version files as well. Where are they stored?

They're not in the bsa's. Background music is in Data\Music, and radio music is in Data\Sound\radionv.

I found with the built in radio's they have two version's, a stereo and mono version of the song. Only thing's in the BSA's are all audio NOT Radio, and even then I think the Radio Voice is in the BSA. I'm fairly certain the BSA's don't contain the radio music for format reason's, or legal reason's. One of the two.
