(hehe, roseanne's funny)
a good band has to have talented instrumentalists as well as vocalists, of course.
the lyrics should be clever written, hiding their real meaning, so that everyone could relate to them, not necessarily thinking about the same thing. "how does the music have to sound?" it really doesn't matter, as long as the banRAB' songs are good. the band should know how to perform live (to be entertaining etc)
