2013 was an amazing year for pop music! Veteran artists pushed the envelope by releasing new albums (and, in the case of Justin Timberlake, two!), while newcomers wowed us with their freshman efforts. The Grammy for Best Pop Vocal Album honors the best of the best. With Lana Del Rey, Lorde, Bruno Mars, Robin Thicke and Justin up for the award, who do you think should win?

Lana Del Rey followed up the success of 'Born to Die' with 'Paradise,' an album that continued to showcase her smokey vocals. The project reached No. 10 on the Billboard 200, while its single, 'Ride,' did well internationally.

Lorde made major waves with her debut album, 'Pure Heroine.' The New Zealand singer raspy voice and disinterest in materialism made her one of the biggest newcomers of 2013. 'Royals' isn't the only gem in 'Pure Heroine' -- the whole album explores Lorde's perspective of growing into an adult.

Bruno Mars' 'Unorthodox Jukebox' spurned hit after hit. From 'Gorilla' to 'When I Was Your Man,' there's no doubt that the album was a massive success. While Bruno continues to impress audiences with his incredible performances, we've got 'Jukebox' in constant rotation.

Robin Thicke was one of the most-buzzworthy singers of 2013. His smash hit, 'Blurred Lines' raised eyebrows while also making the entertainer an artist to watch. His album, also titled 'Blurred Lines,' explores the realization that life isn't, well, black and white.

Justin Timberlake dropped not one, but two albums in 2013! ‘The 20/20 Experience – The Complete Experience’ showed that JT can pull off suiting up with Jay Z, but also that he can get in touch with his vulnerable side, like with his track 'Mirrors.'

Who do you think should win Best Pop Vocal Album? You can vote for your favorite once an hour until the polls close at 7:59PM ET on January 26, 2014.
