I think the best way to get across what I am trying to say is with an example. Okay, say you have a guy like Springsteen (of whom I am a big fan). He is not a bass player (excluding 57 Channels with nothing on). If you read the liner notes he is credited to writing the songs, but isnt there more to it than that? Who is really writing the songs? Sure he provides the basic songs structure but if you take a song like Thunder Road for example, which is not a simple bassline, he didnt write that bassline. I am assuming Gary W. Talent did. But i dont see Gary getting credit for it. In my opinion the bass line is integral to the song. The bassline for a song like Thunder Road is way beyond just playing 8ths on the root. It is a written piece of music, but often it is not credited to the writer. I am not saying Gary is not getting financially compensated, but shouldnt Gary get some of the "glory" for writing the bassline for such a great song and thus helping it become such a great song? This example can be applied to many many band situations. In fact, probably most. I think groups like U2 do it right by crediting the song to the group. "Song written by U2". Isnt it unfair for bass players to not be credited for the lines they write?
