No. None of them are songs. Except perhaps the last one, it's an instrumental version of a known song.
I'm starting to understand where you're coming from, and I guess I agree, but I think you're arguing semantics here.
If the point is to say that Morrissey is responsible for more than just words, okay. That's true. He has an impact on the music that can't be reduced to words and voice alone. I
could state the obvious and counter that on every single Smiths sleeve it reads "Words: Morrissey / Music: Johnny Marr", adding the reminder that Morrissey's use of language is usually pointed, but as I agree with you in principle I won't be so obnoxious as to do that.
Still, however you explain the songwriting process, and describe who is responsible for which element, Morrissey's songs would collapse in a heap without the songs' instrumentals. I don't just mean that Morrissey's voice wouldn't sound as appealing "naked", but that a good deal of the force and power of the music is non-vocal. To my ears, "This Charming Man" would be a
completely different song without Marr, Rourke and Joyce.
If you blur the line between the words and the music, that cuts both ways. We'd have to start talking about the emotional resonance of the synths in "There Is A Light" or the rhythm section in "Shakespeare's Sister". Do the instruments not convey moods, atmospheres, and thoughts just as vividly as the lyrics do?
I think we're ultimately left with the same, boring old concept of the mysteries of band chemistry.
