I can ask the few that I do know - though I'm quite sure of the answer.
And I'm not simply calling everything rock. While I agree that what is and isn't rock can be heavily subjective, I think there are basic keystones of rock - including the strength of the rhythm section, the tempo and time, and the instrumentation and subject matter . . . and certainly much of Steely Dan fits those criteria. If you can listen to those songs I posted, including Reelin' in the Years, Black Friday, etc. (and there are others) and provide a defense of the notion that it's not rock, then cheers mate - but you can't.
So notwithstanding this supposed but unidentified universe of musicians a majority of which allegedly don't consider Steely Dan rock, is there any other basis for saying these songs in particular aren't rock?
