I'd love to think he is an INFP

, but Morrissey is likely an INFJ, IMO. He is far too finicky to be an INFP.
In concert, his physical movements in concert & way of speaking seem more Fe to me. The way he'll put his hand to his heart and speak in an overly polite way.
He also speaks very articulately, and while INFPs express ourselves very well in writing, we tend to ramble and be far less clear in verbal conversation.
He can also be a bit self-righteous, and that's not very INFP.
this makes me think of a chappelle show skit based on the racial draft. i secretly WANT morrissey to be an infj, but in my heart of hearts i'm afraid to get my hopes up. yet part of me considers that maybe he in fact he IS an infj, and it's just all of the Fi (and particularly infps) types i know who love him that is skewing my interpretation.
(also, i don't really agree with some of your diagnostic. i think infps just take a longer time to develop their writing skills than infjs. by the time our tertiary Ti kicks in, our expression is pretty much complete. Fi takes a longer time to get a grip on, writing probably takes a bit more practice, but auxilary Ne is really creative at generating angles and ideas, and ter Si allows them to hold on to specific concrete things to anchor and focus them. we as infjs might read faster/more than infps as a whole, sometimes i feel like i'm scanning the pages and glossing over them more than slowly digesting them. looking for somethin Ni related, whereas Fi is sorting out and meditating on the feeling-tone of each object. infj learns how to adapt speech-voices to communicate with Fe, and it has more of an immediate conceptual insight from Ni dom. i find infj writing as easiest and most natural when it is at its most Fe talky. it is the first way we learn to express/extravert ourselves).
also, for some reason, my Ni tells me that morrissey and leonard cohen are the same. i am questioning that bc i have no reason to believe it, but that is what it is telling me.
i have not thought about brian eno at all, but when you mention him as an infj/enfj it doesn't compute as incorrect. very vast and florid, he is always exploring. plus i think infjs can make great producers. they are probably more me-centric than an enfj producer would be, they would put more of their own stamp on the product, but they can seamlessly blend ideas, concepts, directions. plus based on one interview i read, i felt like he had that look in the eye that infjs can get. views his role as synthesizing vast amounts of (musical) information, and very confident in his big picture understanding/judgment of what is important, relevant, etc.
joey ramone as entp, i'll remember that. i do not know him very well, i've read punk interview books more than i've listened to his music, seen him perform/talk, etc. it's on my to-do list.
