While I like the music in the game, it feels like the same three tracks are getting played with very few exceptions (i.e. Craglorn and Coldharbour). Otherwise it's all this soft winding melodic strings and orchestral deal. There's no dark brooding theme, even in Rivenspire. There's no serpentine oboe track in Alik'r. No jungle drums in Greenshade. It's all just the same mishmash of orchestral -- and again, what is there is quite good; I still enjoy it despite having heard it a billion times. There are just different ways to go with this though and it becomes noticeable after a while that you're always either hearing the same battle theme or the same woman lilting in key with a violin for the bulk of your play time.
A non-critical suggestion that would improve the experience, I think. The zones are unique enough to warrant their own themes.
