Green Day demo leaks

The title track from Green Day's forthcoming "21st Century Breakdown" leaked over the weekend. It sounds like the band built on their American Idiot sound by listening to a lot of Bruce Springsteen and Queen. I doubt this is going to be the first single off the album (which isn't due until May), as it's more than five minutes long and goes through three distinct movements.

I would post a direct link to the mp3, but I am led to believe that could get me in some legal difficulties, so I will just say if you youtube "Green Day 21st century breakdown" you can find where it's being hosted. Let me know below what you think.
