How about playing drums has a RALLY effect that gets any faction you're cool with to tag along and fight by your side for x amount of time?
How about playing certain notes on a lute actually does damage (or status effect at least) to enemies with super sharp hearing.........LIKE THE FALMER?
How about having completed "vocal training" at the college gives you A PERMANENT 25% COOLDOWN BONUS TO SHOUTS?
Seriously. It could have been so much more.
