How do I make music that overrides enemy music?

[Elven]

I might have some amnesia, but 0 is lowest. Try a higher value, can't recall what enemies might have but test 100 or something. Otherwise do as suggested by palistov/photoneus above and make a custom entity file.

Its weird. In my amnesia it works as 0 lowest, 1 higher. I posted that into wiki thread and it seams yet again to many other it works opposite, that 0 is higher then 1 :/
