We officially have a new Pop Clash victor! Last round, the Vamps dethroned reigning champ Charli XCX. This week, the Brits' 'Somebody to You' goes head-to-head with 5 Seconds of Summer's 'Amnesia.' Which song should win this week's Pop Clash?

It's hard not to think of summer when you hear the Vamps' 'Somebody to You.' The sun-drenched track, which features vocals from Demi Lovato, is upbeat, infectious and at the top of our playlists! How can we resist the Vamps crooning about being lovestruck?

5 Seconds of Summer's 'Amnesia' has a totally different tone. The stripped-down track shows a more serious side of the fun-loving band. Heartbreak is palpable as the Aussies wish they could forget a love lost. It tugs at our heartstrings because it's so darn sincere.

Which song should win this week's Pop Clash? Vote for the Vamps or 5 Seconds of Summer once an hour until the polls close at 3PM ET on July 14.
