My Top 12 from 2009 to now is:
Superman Tonight
Beautiful World
Love's The Only Rule
This Is Love This Is Life
Saturday Night Gave Me Sunday Morning
Thick As Thieves
What's Left Of Me
I'm With You
Happy Now
Pictures Of You
Army Of One
BrokenPromiseLand

All of them are 10/10 for me. My vote is for Superman. I don't know why it wasn't big hit.
