If it's fire related - Kerosene: Big Black. It is a bit extreme, though.
In keeping with my philosophy of not being ashamed of any song that I like, I suggest Katy Perry's "Firework."
You know I love that song too. Ultimately, I think the lyrics don't make a lot of sense, but it is so catchy and earworms like nobody's business. I had that in my head all summer.
You haven't heard Firework until you've heard it filked as a pro-WWI propaganda song as part of a suffragism role-playing game in a college history class.
