[Suggestion] The ability to get/buy and then select different music for things:

I know people aren't very fond of microtransactions and I would probably never expect this to happen, but I think the ability to select different musics for certain actions would be cool. The ability to change the music for things like chocobo riding, fights,bosses,fates would be a very interesting way to spice up gameplay or feel that your experience with the game is tailored to you. This of course would exclude specific boss/fight themes.

I, and many others, love the wonderful musics of past Final Fantasies and I love the soundtrack to FFXIV, but eventually some songs might get stale. I figure it'd be a great idea to be able to switch, say the chocobo theme, to any of the themes between 2 through 14. I understand this is pretty much a nonissue and 2.0 has barely been out, especially when talking about adding extra, superficial features, but I was mainly just wondering what people would think of an idea like this.

TL;DR: Buying or obtaining different musics from different FFs to replace the themes of certain things in game to spice up gameplay or give a more customizable experience.
