Contrary to popular belief, this is NOT the spelling of the punk rock band 'Green Day' (note the space between the words).
TeenyBopper: OMG!!! i lurrrrve Greenday.
Me: Green Day? And how would you spell that?
TeenyBopper: G-R-E-E-N-D-A-Y
Me: WRONG! sheesh...

Green Day is a seriously kick ass band. No matter what anyone says, they aren't sellouts...and i seriously hope they never become sellouts...i don't much cre for american idiot (except for boulevard that song kicks major ass), but that is just my personal opinion...and anyone who has their album Warning check out castaway that song is so under-apprecciated and shoulda been on their international superhits album.
International Superhits, Dookie, Warning, Nimrod, American Idiot...

A once kick ass punk band
They started out as "Sweet Children" Playing an infamous punk club called gillmans street
later touring the u.s. and making two albums before releasing a punk masterpiece: Dookie
This did attract a lot of younger people and the people of gillmans street labeled them sell outs

In response Green day released Insomniac

A bit like dookie except a bit harder and faster

Then after that i call the downfall
They released Nim rod: A weird experimentation of Green day's sound then they released Warning
A bit more "poppy"

Then they released the all terrible: American idiot which they are now known for
If you really apreciate green day

you would of liked their first four albums
1. 39/smooth

2. 1,039/smoothed out slappy hours (combination of first album and EP's
3. Dookie
4. Insomniac
Girl: ZOMG BILLIE JOE IS SOOOOOOOO HAWT!
Me: You have failed to recognize the true talent of green day

A really good band. For those of you people who are saying that American Idiot is just all politically related, you are completley wrong. It says the real way of American living. Normal people have to deal with drugs and sex and real life problems everyday(streets, schools, etc). They just say what they really think about American people and life. And for those of you that are saying that Billie Joe can't sing live, you need to have an ear checkup. He sings really good. Just because they have some stupid teenyboppers and posers saying they are hot and sexy doesn't mean they are a poser or bad band. That's not theirfault. You have to actually listen and hear their songs and lyrics to see they are an excellent band. They say what they really think and I think that their albums are great. And If you hate Green Day well, this is just my opinion, and you have to respect that. And if you hate Green Day that much well then don't listen to their songs and don't be wasting your time posting nasty stuff over here. Cuz they don't even care what you think
I think Green Day is a really good band. If you don't like them, I don't care.

A band is not punk,used to sound punk, but now are mainstream/alternative rock, others might include A.F.I. and Blink 182
Green day could care less about what music they play so long as they make a lot of money
