Popular Pakistani singer Najam Sheraz has lent his voice to singer Udit Narayan's son Aditya for his film 'Shaapit'.

Filmmaker Vikram Bhatt's 'Shaapit' is his next spooky horror film; the last release being '1920', which had a decent success at the box office.

Apart from acting as a mainstream hero, Aditya Narayan has also done playback singing in the film.

However, the song 'Tere bin jiya jaaye na' sung by Sheraz, who has even written the lyrics of the song.

This makes many wonder that despite Aditya Narayan's playback songs, why was Najam chosen to do a song too in the film? Guess its Vikram Bhatt's knack for good music.

Well, whatever be the reason, the songs in the film by both the singers are competitive and gaining popularity.
