In an online poll for Rolling Stone, Green Day won “kings of punk”.
Green Day is not punk and has not been punk for nearly 20 years. More than that, none of their “influential” material is remotely punk. What songs are they known for? “Time of Your Life”, “When September Ends”, “Boulevard of Broken Dreams”. Sure, there’s “Basket Case” and the title song off of “American Idiot”, but those are more anomalies than anything. Green Day is a pop-rock band that’s ridden fame along sappy songs and high school graduations that play “Time of Your Life”. That people voted them KoP over Black Flag and The Clash is just blasphemous.
Final note: if you have a Broadway show, you aren’t punk.
