I guess the only reason why I'm making a big deal out of it is because the last band I was in I didn't get any credit, for co-writing because the bass player came up with most of the parts (on bass only), and I would help piece them together or make changes or add new parts.
Its not my ego! But in 3 months we have 10 complete songs, that kick ass, that me and the other guitar player spent alot of time on. It's kind of like we did most of the work. And since we both play bass, we have been thinking of writing his bass parts, although I don't know how the bass player will take, but that's probably for another thread.
