Tiesto @ Citywalk OKC - What song was this?

[FuManChuu]

Sorry guys, this is a huge shot in the dark... but I can't find a better place to ask than here.

I was at the OKC Tiesto show on Monday, and the house DJ before Tiesto came on played a couple songs I had never heard, but obviously everyone else had. If anyone was there, or anyone has any input on what these could be, I'd love some feedback.

The first one was during the long haired DJ was playing... had something to do with "set on fire" or "light the fire"... and everyone seemed to know the chorus, so I'm assuming it was pretty popular.

The other was one the heavier balding DJ was up, it just involved a 30 second synth keyboard solo, that he would air piano the keys each time the chorus came around.

I know the second is horrid vague, and if no one was there, this is probably a lost cause... but thanks in advance for any ideas

Tiesto was amazing btw
