Could this be the summer song of 2014??
5 Seconds of Summer is an Austrailian band comprised of four young guys. Very young. They were only 15 when the band formed in 2011 (which means they're 18 now haha).
They are currently the opening act for One Direction's tour.
I, personally am loving this song! The video is fun and goofy...who doesn't love people in their underwear!! :)
