It's not complicated but India's first Facebook love story gets a song that best captures the feeling of falling in love online, on Facebook.

Mujhse Fraaandship Karoge (MFK) released one of the most hummable tracks of the year, 'Uh-Oh! Uh-Oh!', on Wednesday.

Scored by Raghu Dixit, the track is sung by Ash King and Shilpa Rao and the lyrics have been penned by Anvita Dutt.

MFK is a romantic comedy set against the backdrop of social networking.
