Crossfire music download

I'm not sure what is the legal standing of music used in Crossfire, but is there any way to acquire it?
I'm interested in music used in Custodian and Utopia systems - I have searched a bit on the internet, but I haven't even been able to find the names of the tracks, let alone the music itself.
If the music is copyrighted and require payment I am willing to pay for it as these tracks are too good to pass by.
