New week, new Pop Clash! After inducting Justin Bieber and Cody Simpson's 'Home to Mama' in the Hall of Fame, we've got two new competitors. Austin Mahone's 'Waiting for This Love' is up against Jessie J's 'Masterpiece.' Who should win the Pop Clash?

In one word, Austin Mahone's 'Waiting for This Love' is steamy. Not only is he channeling a mature sound, complete with mature lyrics, Austin is throwing down a serious falsetto. The best part? He totally pulls it off! It's safe to say that we'll have this one on repeat from now until forever.

However, if you're looking for that one jam to boost you up when you're down, you've got to give Jessie J's 'Masterpiece' a listen! “I got a way to go / But it’s worth the wait," Jessie belts, reminding us that even pop stars with hit songs have rough moments. And it's Jessie's charisma and incredible vocals that solidify this for us.

Who should win this week's Pop Clash? You can vote for Austin Mahone or Jessie J until the poll closes at 3PM ET on Dec. 29.
