I will do a group round and a knockout round.There will be a group A,B,C,and D.The winner of group A will play the runner-up of group B.Same with C and D.In the group round the first band to get to 10 votes wins and same with the knockout round.
Led Zeppelin is a legendary band that never gets old no matter how much you listen to it. Green Day has always been one of my least favorite bands. I've never really been a fan of punk-rock, and Billie Joe's voice is one I can't listen to without getting angry.
I much prefer Led Zeppelin, because Jimmy Page is an amazing guitarist and their songs are all quite catchy. Green Day is just another band to me, but Led Zeppelin is a godly musical act.
