have a question about the supcom music download

[Nalessa]

Just a little question about the supcom download in the FaF wiki.

Will replace all FA tracks while playing FA, or will I now hear both original Supcom and the FA tracks (I love Rhiza's offensive, but I also love One world at a time, those 2 are just so awesome to listen too, I'm hoping this will allow me to listen to both while playing the game)

And does it apply to playing campaign or skirmish aswell, or only FaF maps?
