Sometimes you'd like to listen to X music on Y mount. Some mounts are more aesthetically pleasing, as well as some songs being better than what's forced on them.

Edit: Not to mention there's a decent bit of mounts that play the same music when on them. I have 50 mounts but much less than 50 different tracks to listen to, seeing how there's over 140 orchestron rolls in the game.
