Can you be serious? Firstly, you're comparing two songs that sound nothing alike, and two, Billie Joe does not sing about his 'hays' and 'wows', if you were a true music fanatic, you would understand the whole concept of what the punk rock band itself is trying to say . The whole point of American Idiot and 21st Century Breakdown is the message BJ and co. deliver through their politically charged lyrics. Their live shows aren't just the best 1 hour/2 hour sets that any punk rock band, or any band, have ever conducted in the last 10 years, but is a theatrical work of art. There work isn't just about the amazing sounds that come out of their guitars, but about the whole show itself. Have you ever seen them live?
So what if the media have replayed this song thousands of times on the radio and probably tried to melt it down to another 'mediocre' slot on an early morning breakfast show, but you have to understand the true background of 'Do you know your enemy?'.
For once, stop listening to the 'nice sounds' of a song, and focus on the message itself, then you might appreciate the band a little bit more. If you have done this and not succeeded, proceed in comparing rock giants to pop bands, and resume in joining the rest of society of comparing bands like Green Day, to Justin Bieber. //Rant Over//
