Song of the Summer? Meghan Trainor Is "All About that Bass"

While the title of "Song of the Summer" is still up for debate, Meghan Trainor is making a go with a delicious new single, "All About that Bass."

After penning tracks for Rascal Flatts and Common Kings, the Nantucket native is stepping out of the shadows with a sound that mixes '50s R&B, bubblegum pop and hip-hop. Her first effort hits it out of the park with an addictive record that embraces the booty.

For her debut video, Trainor teams up with video director and choreographer Fatima Robinson and Vine superstar Sione Maraschino to create a retro pop world that makes you want to dance in your seat.
