YouTuber earlvin14 combined 5 Seconds of Summer's debut single, "She Looks So Perfect" with One Direction's song "Kiss You" - and the result is pretty great! Check out 5SOS + One D below.
Okay, move over boybands. 5SOS is a little more 'rock' than you may realize, as evidenced by their raucous cover of Green Day's "American Idiot." In fact, the guys count Green Day as a big influence on their music.
Check out the cover and let us know what you think!
