Disclaimer: It is impossible to watch 5 Seconds of Summer's 'What I Like About You: Live at the Forum' music video without rocking out like Taylor Swift.

As if we didn't know it already, the insanely amped up vid proves beyond a shadow of a doubt that Luke, Calum, Ashton and Michael are total freaking rockstars, commanding the adoring audience and delivering a performance so killer that it has us digging our graves and coming back to life all over again.

Considering the fact that we've been obsessed with their cover of 'WILAY' since they performed it at the 2014 AMAs, this music video has basically blessed us with everything we could've ever wanted. It's filled with black-and-white, so-good-it'll-melt-your-face-off footage from the band's show at the Forum in L.A, plus backstage clips of the guys getting ready and goofing off. (Nice boobs, Mikey.)

It is EVERYTHING, and once you watch it (on repeat), it isn't hard to see why. Slay on, 5 Seconds of Summer. Slay on.
