At one of our parent companies other website, Diffuser.fm, Keith Hopkin recently wrote an article called, "13 Songs That Sound Just Like Green Day Songs".
I'm not going to include all of the examples (apparently, 21 Guns sounds just like every song ever recorded). But, some of these examples sound insanely similar. In fact, too similar to be mere coincidence. I think you know what I'm hinting at here: Green Day are actually time-travelling Chrononauts who used a portal in the fabric of space time to go back and influence some of the greatest bands of the 60s, 70s and 80s! Why do you think Billie Joe Armstrong has Liza Minnelli's hairstyle?
