Since the Primal ponies now have respective music attached to them, why not have the beast tribe mounts have music attached to them as well? I'm speaking of the palanquin, drake, elbst, and goobue that are available through daily rep quests.

I suggest the stronghold's music ( example ) be used when riding any of the mounts, rather than the one used when speaking to the questgivers ( example ). It'll be a good way to get people to do this content again as well.
