Green Day has released another three cord classic, entitled Know Your Enemy. I like the new song, because it sounds better than that schlop "Wake Me When September Ends."

The single is off their new album 21st Breakdown. Fans can pre-order the album on iTunes now and receive four bonus tracks, two of which will only be included in the pre-order. The limited special edition vinyl/CD art book is also available for pre-order rand features the full length CD, three 10" vinyls and a special book containing 60 pages of unique album art. These special editions are limited to 3000 pieces and a guaranteed one-time pressing.
