It would depend which songs, though. You couldn't sensibly remove "How Soon Is Now?" and substitute Roy's Keen and end up with a better list.
This is an interesting thread, actually, in part because of the lack of responses, and the seeming concensus that in five years the Smiths barely put a foot wrong. There's barely any fat on any of their record releases. The covers towards the end, which pissed off Marr so much according to reports, are less impressive perhaps, but still eminently listenable.
I think it is fair to say that thirty years of Morrissey as a solo artist has yet to eclipse the Smiths, although of course he's had many, many great moments.
