Mount Music

1. Extract MountMusic into _retail_\Interface\AddOns\.
2. Put your MP3/OGG songs in MountMusic\Music\.
3. Restart WoW and enable the addon.
4. Type /mm, select a mount, enter a song filename or Blizzard FileDataID, and save.

This addon will play different songs or Blizzard sound files based on which mount you are mounted up on.  Saved settings are across your entire account, and not character specific.  This was an idea I had from when I played Final Fantasy XIV, and each of their mounts had special mount music that will play when mounted up.  This allows more customization to that idea by allowing you to play your own audio files or use Blizzard's audio for more thematic traveling.

Have fun!
