Coerthas Central Highlands Night Music for PC

I found out that for PS4 version of Final Fantasy XIV, there is a night time music for Coerthas Central Highlands. It is actual Final Fantasy XIV: A Realm Reborn music, as it was used in a promotional video by Square Enix for the tour of Eorzea. Is there a way to enable that music for the PC version?

This is an example of the point where the day music is going to change to night music, no apparent hacking:

This is the same example of the night music itself:

This is the promotional video, FINAL FANTASY XIV: A Realm Reborn - A Tour of Eorzea, Part 1, with the very music in play.

That music is the mount music. If you use mounts that are not chocobo and you have the mount music option enabled, it will be playing that music when you ride a mount no matter where you are and what time it is.

Yup that mount music not area music.
