It's actually a combination of three EP's, all of which were recorded before Tré Cool was the drummer.
It's one of those songs that I can't listen to all the way through. I usually listen to half of it, then I change the song. Meh, it just bothers me somehow.
Have you seen the music video for 21st Century Breakdown? It is the best music video I have ever seen. It's just amazing <3
