The Gold Saucer track(regardless of where it came from, yes I did play FFVII, it was my first FF) is too imposing. You can't just afk in game, wait for GATEs and do something else, the music is too loud to do other things on your PC while you wait for MGP grind GATEs. While I was grinding MGP I always turned my own BGM off(also, why are sound effects included in the BGM? Turn off the BGM, turn in some things for Seals and wonder where your sound effects go :/).

Maybe they could just remix the original Gold Saucer track for FFXIV. It is not the FFVII version of the Gold Saucer, add some Eorzea flair to the track and make it more mellow for those long grind sessions?
