Not everyone is a PC gamer. And even with media player the music cannot change for every event.
I don't know a single person who likes the current Final Dungeon Boss BGM.
I personally and burned out the default Battle bgm.

My god people...folks keeps saying they want variety yet when folks make suggestions you attack them blindly.
This is why you can't have nice things.

The 1 thing I remember multiple folks liking about the FFXIII & FFXI events was the music. So why not have an option to use it in game?
Finally. To hell with you all. The post is aimed at the Devs, I posted in General so folks could suggest/add FF titles that had BGM they enjoyed.
