Music Customizing

During the short period of time I played FFXI someone mentioned to me that they customized their music and I immediately looked up a guide on how to do the same! Do you customize the music? If so, do you like to put in music from other Final Fantasy titles?

I had the wizardy starting village (I forget the name!) as Eruyt Village and the party battle theme as an orchestrated version of Don't Be Afraid :3

I did not know you could do this. Were I to play, I would do this to get rid of Vana'diel March. I hate that horn.

I never knew you could change it but I don't mind because the music for FFXI rocked most of the time.
