Green Day have posted six songs from their May 15 album 21st Century Breakdown (read SPIN's review here). You can hear the songs here. They originally aired during a special segment of Los Angeles radio station KROQ's Kevin and Bean Show.
The tracks are from each of the album's three acts ("Heroes and Cons," "Charlatans and Saints," and "Horseshoes and Handgrenades"), offering insight into the band's latest rock opera -- a conceptual record that rivals American Idiot. Frontman Billie Joe Armstrong rails against organized religion and political corruption, among other things.
Armstrong explained his approach to songwriting during the radio segment: "If you're writing topical songs or political songs or rebel songs or whatever you want to call 'em, it's important for them to come from the same place as a love song would come from because you want people to draw their own conclusions. It's just like capturing a moment."
