I can only read tab. But i wish i could read staff. The more you know the better so if u have the time then of course learn staff.

Plus i like the idea of how you do not have to listen to a song to get the beat which is a big advantage.

I also garuntee you that if you were to go somewhere, where there is some REAL muscians (not just people who play guitars), and then this topic comes up, then im sure that you would be laughed out of the room. :)
