Ariana Grande "Baby I" (Ryan Pallotta, dir.)

Nickelodeon star Ariana Grande is well on her way to making a legit pop-star crossover, thanks to a song that hits you like the girl re-write of Bieber's "Baby" and a soaring voice that's in the zone of Mariah Carey. Director Ryan Pallotta engineers an all-day and crosstown dance party that takes Ariana and her crew into the night.

PS: Does the styling count as '80s retro/ironic if the singer was born in 1993? 

Michael Buble "It's A Beautiful Day" (Marc Klasfeld, dir.)

Michael Bublé - "It's A Beautiful Day" [Official Music Video]

It doesn't start out as a beautiful day — unless you think Michael Buble is used to coming home to find his wife (played by Jaime Pressly) locking-lips with professional geek and noted make-out artist Jesse Heiman. Things don't get much weirder than that, but they get a lot more chaotic in this homage to maintaining a zip-a-dee-doo-dah attitude, no matter the situation.

New Kids On The Block "Remix (I Like The)" (Rami Hachache, dir.)

New Kids On The Block - Remix (I Like The)

Can New Kids On The Block inspire The Lonely Wallflower to become the life of the party? Not a problem. These Boys To Men rock a bit of a Suit And Tie vibe as they get It's Always Sunny In Philadelphia actress Artemis Pebdani to liven up an other demure house party.
