So I just heard Panic! at the Disco's new song...

[lr2942]

It's called The Ballad of Mona Lisa and I nearly cried. :,)
It's almost the same as before they split.  

[Im Siwan]

The video's one of my favorites, too! People on tumblr have been comparing its similarities to 'I Write Sins Not Tragedies'.

Still, it's a great single!
