I agree that this is too hard. I'm not going to throw up a list of "less-popular-oh-look-I'm-a-hardcore-PJ-fan" songs, because I love the popular ones. I might not like them as much as most people, but Last Kiss is an alright tune for a throw-away cover.
It's funny, I think I stopped listening to Ten the more I started getting into. Not to say that it's not a great album, but there's a ton of other great PJ stuff out there that people should really check out.
Other songs I love in some kind of chronological order I guess:
Porch
Evenflow
Jeremy
Once
Small Town
Go
Yellow Ledbetter
Daughter
Rearviewmirror
Animal
Nothingman
Curdoroy
Not For You
Whipping
Spin the Black Circle
I Got Id
Hail, Hail
Present Tense
Given to Fly
MFC
Breakerfall
Nothing as it Seems
Grievance
Save You
1/2 Full
I could throw a lot more in there and I probably forgot a bunch, but those are just ... highlights I guess.
