Ladies and Gentlemen, meet the new C & C music factory -- pop newbie Colbie Caillat and debonair rapper Common. The Ryan Tedder-produced 'Favorite Song' is the two-time Grammy-winner's metaphoric love ditty that features playful electric guitars and feel-good lyrics.

Caillat's sing-a-long chorus is especially catchy, as she sings: "I want to be your favorite song/ You can turn it up/ Turn me on all night long/ I want to be your favorite song/ La-la-la-la, la-la-la / I want to be your melody/ Going through your head when you think of me/ I want to be your favorite song/ La-la-la-la."

Meanwhile, Common's lyrics are just as softhearted as Calliat's as he tries his hand at crooning. "Girl the songs you sing / They my favorite things / You stay in my dreams / Something so supreme," he warbles.

Later, the Chicago emcee co-signs their sumptuous duet. He raps: "We stay in tune with each other / And in our room we will discover / New ways to do covers / No matter how they dub us / We should stay true to the trust / And the winner of the best duo/ Is us."

'Favorite Song' is the perfect sunshine-y ballad for the summer and it will most likely do well on Hot Adult Contemporary radio. And if you're looking for some feel-good island music for your next beach party, go pick up Colbie Caillat's new LP 'All of You,' which is in stores now.
