Congrats to Justin Bieber and Cody Simpson! The duo's 'Home to Mama' just locked in its third Pop Clash win. This week, the collaboration faces off against Taylor Swift's 'Blank Space.' Which song should win the Pop Clash?

Two of our favorite singers joining forces to sing an emotional and vulnerable track? It's impossible to resist Justin and Cody's 'Home to Mama.' Not only do the two sound amazing together, but it's a mature track that is a step forward for both of them. We couldn't be more excited for whatever they do next!

With all of the media attention on her relationships, Taylor Swift turns the tables with 'Blank Space.' It's a tongue-in-cheek track that exaggerates the rumors surrounding her love life -- and it's really, really catchy. Whether your relationship is going to last forever or go down in flames, you can definitely jam to T. Swift's newest hit.

Which song should win the Pop Clash? You can vote for 'Home to Mama' or 'Blank Space' until 3PM ET on Dec. 8.
