Me and a FC buddy were talking about what we could do with the FFXIVAPP Event plug-in and it came to me that I could play the Terra theme song every time I use my Magitek mount. It works!
The app actually bugs out every time until the song ends. And there is no way, that I know of, that could end the song when I dismount. Obviously this app was not design to do this, but it's still fun.
