This uses music from TOR. And Fair Strides didn't react after HK-47's statement that he took them from CD. Maybe Customer Service will know more about the situation with SWTOR online soundtrack. I'll contact them later.
It's not for me to decide but I'd remove this mod then since from my understanding this is not allowed.
For the mod: I'd simply use TSLPatcher with several installation options:
1) Czerka Music for Anchorhead
2) Dune Sea Music for Anchorhead
3) Custom Track for Anchorhead
4) Custom Track for Ebon Hawk
This way the mod installer would need to edit only one entry in one file and in the last two cases instructions for making the corresponding audio file would be given.
And if no one beats me to it I'll definetly make that mod next weekend^^
