I actually really like Kill Uncle aside from "Asian Rut" and what makes it worse is that it's the second track and really dampens the record early on. The other thing about Kill Uncle is it's I believe by at least 7 minutes Morrissey's shortest record proper as is, so one would need to replace the track with something half decent. Peculiarly the K.U. sessions seem to have been rather lean compared to most other album sessions and who knows what would be left. I'd settle for "Journalists Who Lie" and "Tony the Pony" I guess, just to bring it up to par length wise.
"Found Found Found" is great in my opinion; a bit of a prelude to the Your Arsenal sound. If it was a bit longer it would probably be more well rounded and honestly could have been a single. Incidentally I believe contrary to common belief that Morrissey is imploring someone to be with him "all the time" rather than complaining that someone is overbearing... after all he and Jake were definitely of the "all the time" nature.
Your Arsenal and Vauxhall and I really have no weak tracks (the former is the only record in the world I would give a 10/10 rating) but with Vauxhall and I one could relegate one of tracks 8, 9, or 10 and it wouldn't make the record weaker per se.
His debut is fairly solid. One could switch tracks 10 and 11 in order and drop the final track and it wouldn't hurt the record though.
Southpaw Grammar's long tracks are a few minutes too long and with only 8 tracks the condensing of those two behemoths would require the addition of another track or two ideally ("Boxers" and "Sunny" would have worked).
Most of Maladjusted (despite flashes of brilliance), Ringleader of the Tormentors, and Years of Refusal are non-essential listening aside from a few tracks.
I actually think despite the production that You Are the Quarry is pretty darn good (despite the production) if you drop "All the Lazy Dykes" and maybe "How Can Anybody...". The thing is the record's length really waters it down by the second half. You Are the Quarry really begins Morrissey's quantity over quality era which unfortunately has persisted.
