The song is heavily leaning towards punk rock, as part of Billie Joe’s New year’s resolution to “destroy the phrase pop-punk forever”. It has all the elements of a good ol’ punk rock song, the lyrical themes, the loud fast–paced music, the attitude in the vocal performance, everything. It’s your typical post “Warning” Green Day song. Just get 5 seconds of the song you will definitely know it’s a Green Day song.
So far, the two singles haven’t been able to meet the undoubtedly -totally reasonable- sky-high expectations of punk rock fans, some of them are even counting on this comeback to regain punk rock’s lost position in TV, Radio and music charts. The songs are just not that good of compensation to those last 4 years of total disappearance, but who knows? Maybe the album will be.
Finally, If you’re a Green Day fan, here’s a piece of advice, do not expect the song to completely overwhelm you the first time, give it time, it will take it’s time to grow on you then you’ll absolutely love it, just like what happened with ‘BANG BANG’.
