I'd be great if the mount Nightmare had music too when you ride it, some nightmarish music. And to make Nightmare fly/swim too. It's my favorite mount in the game but you cannot fly/swim with it which I find really sad, I can only ride it in 2.X in the main basic game and not at all in the expansions. And I find the lack of music pretty sad too.

PLEASE FIX NIGHTMARE!
