Query: Best Green Day CD

This CD is just so cool. All of the songs just have so much substance. It's so fantastic. I love the lyrics and the tune of the songs. I love how they did different things on this album. The way that they put so many different instruments in is totally cool. I agree that each song could stand as its own album. It's just the best album that I have heard in a long time. I suggest you buy this immediately.
