First, listen to 5 Seconds of Summer's new banger, "Permanent Vacation."
For those not in the know: 5 Seconds of Summer kicked off their first ever worldwide, headlining arena tour in Lisbon, Portugal, and the the lanky lads debuted a new song live. It's titled "Permanent Vacation," it's pretty Michael Clifford/Luke Hemmings–heavy, and you can listen to it above.

When we first heard "Permanent Vacation" (in the form of blurry, low-def live Vines, just like you, 5SOSfam) we immediately thought Green Day. At first, our minds jumped to the American Idiot–era, as that's the record and timeframe 5SOS is most familiar with. On second (who are we kidding here...and third, fourth, fifth, twelfth?) listen, we realized the tune directly grabs from Green Day's '90s hit "Longview."
