Being totally serious, the closest thing to Dragonforce is "happy hardcore" dance music. Like this:

except Dragonforce use guitars instead of gay keyboards. Actually, I can listen to happy hardcore more than I can listen to Dragonforce.
I still don't understand why they're classed as metal, when they're more like the sort of shitty dance music neds/chavs drugged up on E listen to while driving around in their little boy-racer cars.
Fuck Dragonforce, they're a horrible band and they give me a sore head with their constant fucking "Happy happy joy joy" bullshit.
