Both are important but

-Learning music reading and not having the talent (which I call the musical ear) will not make you a good musician
-Having the musical ear and not learning how to read music can still make you a good musician (with all due humbleness I am a living proof of that).

I won't deny though that I would love to be able to sit down and have a sheet music infront of me and just play it without having to have pre-listened to it. I wonder though, will I give it he same feeling as having listened to it and felt it before playing it?

My two cents.
