The 59th annual Grammy Awards air on Sunday, February 12, and they're set to honor the best and brightest in music. While fans do not have a say in the official outcome -- the Recording Academy ultimately votes for the show's winners -- you do have the power of expression, which begs the question: Who deserves the Grammy Award for Best Pop Vocal Album?

This year's competition is fierce and includes albums from some of pop's biggest stars.

Justin Bieber's comeback album Purpose -- which is also nominated for Album of the Year -- is the only male artist nominated for Best Pop Vocal. He's up against powerhouse vocalists like Demi Lovato (Confident), Ariana Grande (Dangerous Woman), Adele (25) and Sia (This Is Acting).

But who, above all others, deserves to take home the award for Best Pop Vocal Album?

Vote in the poll below to make your voice heard, and be sure to tune in to the Grammys when they air on Sunday, February 12, to find out who wins!
