According to the singer and TV host, these days, the song a singer sings may well be re-dubbed by someone else even before the film is released.
Describing it as a "sudden trend" in Bollywood, Shaan, best known for songs such as "Jabse tere naina" from "Saawariya" and "Chand sifarish" from "Fanaa", said he cannot be sure any more about his songs till a film is actually released.
"Just yesterday I got to know that a song I had sung for a big production house has been re-dubbed; someone else is singing (it)," the singer claimed.
"It is tough to say which songs or projects are there until a film releases. Sometimes, we also unknowingly re-dub someone else's song. So until a film (releases) it is tough to say anything," contended Shaan, who began his career with ad jingles and re-mixes.
Another trend Shaan has noticed is what he calls the return of the "Indian feel" in recent Bollywood numbers.
"I feel that the melody and Indian feel are coming back into songs. People are liking them; it's a good thing," says the singer who has also given us hummable numbers like "Tanha dil" and "Behti hawa sa tha woh".
