5 Seconds of Summer may sound completely pop with their hit 'She Looks So Perfect,' but don't ever doubt that these guys can rock. And if you weren't convinced enough after their killer performance at the 2014 Billboard Music Awards, you need to listen to their cover of Green Day's 'American Idiot.' Now.

Kerrang! magazine has enlisted some awesome bands (yes, including 5SOS) to come together for a tribute album in honor of Green Day's 'American Idiot.' While 5SOS covered the record's iconic title track (more on that below), other groups like Bowling for Soup and You and Me at Six covered other songs on the album like 'St. Jimmy' and 'Are We the Waiting.'

What makes 5SOS' cover so amazing is the passion that the band pours into the song, jamming out crazy hard on those electric guitars but still harmonizing like nobodies business, even as they sing their hearts out on the track.

There's a reason that 5SOS' Green Day cover spawned multiple trending topics on Twitter today -- simply put, it's amazing. Listen to it below!
