The MTV Video Music Awards are less than a month away and we can't wait to see who takes home the Moonman for Best Pop Video. This year's contenders are making the race especially tough! Will it be Bruno Mars, fun., Justin Timberlake, Miley Cyrus or Selena Gomez?

Bruno Mars went retro with his video for 'Locked Out of Heaven.' From the fuzzy quality to the melody reminiscent of the Police, this video showed an old-school side of Bruno that we're diggin'!

Following party songs like 'We Are Young' and 'Some Nights,' fun. took it down a notch with 'Carry On.' The video reflects the more serious tone of the track, showing the guys playing for enthusiastic bar crowds and encouraging them to push through the hard times.

Justin Timberlake also got "reflective" with his video for 'Mirrors.' As JT sings about his other half, the visual shows a young couple and an elderly couple at different points in their lives. Deep, right? We'd expect nothing less from Justin.

In contrast, there's nothing subtle about Miley Cyrus' 'We Can't Stop' video. The singer raised many an eyebrow with her twerkaliciously bizarre visual. From teddy bear backpacks to that doll in the swimming pool, 'We Can't Stop' confirmed that there is no way Miley's going back to Disney.

Selena Gomez got exotic for 'Come and Get It,' the Indian-inspired lead single from 'Stars Dance.' The video highlights various sides of Sel's mature image, showing her singing in the mountains and provocatively dancing in firelight.

All of these videos are amazing, but which stands out the most? You can vote for your favorite once an hour until the polls close at 8:59 PM ET on Aug. 25.
