I don't know, man... I have a pretty intense love for music too. I mean, eyesight would make living everyday life easier... I'd choose eyesight, but hearing isn't far behind eyesight is what I'm trying to say.
hearing is way more important to me. music is my life. playing it and listening to it. i can adapt to being blind and reading brail, but i can't adapt to a musicless life.
definitely eye sight, i was thinkin about that the other day, if i went blind, i could still do most if not all of my job. and i could still see stuff.
