I'll concentrate on post-2000 specifically, since that's basically a catastro****.

and most recently...

Any Other Day. Simply stunning how Jon has shunned this song totally. Why would he? He knew it was getting indications of being a big hit, Richie loved it, it was awesome live. Why was it never considered for a single (never mind the fact they seemed to have taken it out of the sets)? I don't even think it's because Jon dislikes it, because he's not stupid: if a song has business potential, he'd go for it. The answer is far more obvious: he has trouble singing it.

Shame.
