The Wanted are proving to be an unstoppable force in PopCrush's weekly Sound Off series! After a heated battle and thousands of votes, the British quintet's smash hit 'Glad You Came' beat out Katy Perry's new single 'Part of Me' with more than 53% of fan votes. Now, this week, the Wanted will take on fellow U.K. star Adele and her brand-new '21' single 'Rumour Has It.'

The Wanted kick off their upbeat, Eurodance jam with somber piano keys as Max George smoothly croons the opening line of the chorus. 'Glad You Came' quickly changes directions, however, with the guys harmonizing about finding love over the synth-laden, effervescent dance beat. On the contrary, Adele's majorly ticked off on 'Rumour Has It,' and the pounding drums, spiteful lyrics, and powerful vocal performance reflect just how much this Grammy-winning songstress hates being the center of gossip and drama.

In this battle of the songs, which track do you prefer: The Wanted's 'Glad You Came' or Adele's 'Rumour Has It'? Cast your vote below! The poll will close at 8AM EST on Monday, Feb. 27.
