Anything with a 1980s Indie Guitar Jangle will probably put Mr Morrissey back into success, that's what I think anyway. It's what made Morrissey famous and its what would probably please loads of fans!
Bring Back The Jangly Guitars!
I don't think he's ever been about "success" or "pleasing loads of fans." I really don't understand what it is about some people and living in the past. What he did then was good for its time. I'm not saying what he's doing now is the BEST he could be doing for now, but that's only because the past couple years he's been using a pretty standard sound consistently -- at least with YATQ and YOR. I've said it once, I'll say it again: he needs to do something completely new to remain relevant.
Also, it amuses me how the topic of this thread was to develop discernible characteristics to differentiate between each of the styles of the respective songwriters, and for the most part, "Jesse's songs suck" counts as a purely objective trait.
Those of you who are actually contributing something other than your own opinion, good on ya
