It's been a while, but Green Day is back with a new album. 21st Century Breakdown is their latest album since American Idiot came out about 5 years ago. The guys have been around for a while and 21st Century Breakdown shows that they haven’t lost their touch. Listening to it, it sounds like most other Green Day albums. But hey, we’re talking about Green Day here! On all of their albums you’re guaranteed to hear that trademark pop-punk sound of theirs. Overall, while it’s not the best Green Day album, 21st Century Breakdown has plenty of fresh material to make it a hit.
