Here's how we play:
Someone'll put the Beatles and the Stones in the rival bands boxing ring. Who wins?
So you'd say, "the Stones!" ...but you'd feel a little guilty about it. ;-)

2nd example:
Clash vs. Sex Pistols

The Pistols come out swinging hard in the first round, punch themselves out and get knocked out in the middle of the third round.

Ask and answer.

I shall start things off with a few battlin' bands:

Oasis vs. Blur

JAMC vs. BRMC

Interpol vs. Joy Division

Razorlight vs. Libertines

EATB vs. U2

Don't really gotta be "rival" bands. Kin be Depeche Mode vs. New Order, get it? Oh, and you can't answer your own battling bands.

"OK, now. No hitting below the belt. Bands can't be saved by the bell. I wanna see some good clean bloody violence." Let's get ready to rumble!
