Hey I learned right around 100 tunes over the course of last summer. One band had me learning Zeppelin, Queensryche, Megadeth. The other was top 40 rock, CCR, John Cougar, Billy Joel.
The metal band ended up letting me go( bass players are not required to think, just play) which bummed me out but I came out of it a better player with far more confidence because I pushed myself and came to the conclusion that I'm a better player than I thought.
When did it become a waste of time educating yourself for the sake of self-improvement?
