That piece describes the Roller Beetle so well! The whole track is like musically driving the Roller Beetle, first part is like powering up the speed-up button, and when there is this culmination point it's like driving on the highest speed, and then the last part is like drifting and then stopping.
I listened to the song while driving my little Bug, and I can confirm, that it really fits the whole, nice experience that this mount gives.
But is there a chance to have a theme for other mounts too? There is High Roller and Desert Skimming and Reins of the Raptor. Any chance for Griffon, Jackal and Springer's themes?
The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown.
