After Dev D, Anurag Kashyap is back with a musical love story Manmarziyaan. Promising to be the album of the year, the film's music composed by Amit Trivedi is already a subject of heated discussion.

In a unique promotional strategy, the makers are releasing one song each day and audiences were in for a treat as the first song 'F for Fyaar' marked actor Vicky Kaushal's singing debut.

Such was the reception that the song went on to cross 7 million views in less than 8 hours.

Talking about the idea says music director Amit Trivedi, `Since Vicky plays a DJ in the movie, we felt it would be great if he could sing a few lines in the song to give a real feel to it. It has come out well. When Vicky heard the song, he was pleasantly surprised to hear his voice. He enjoyed the singing process.`

Excited to be teaming up with his mentor again says Vicky Kaushal,`I am very excited and I have said this to Anurag as well, but I feel like I should collaborate with him once in every two-three years because he really makes you reinvent yourself as an actor, which I feel is very important for me. Each time I work with him, I see something new in myself and that's what happened in Manmarziyaan as well.`
