"Najane Kyun" (Urdu: نہ جانے کیوں, literal English translation: "Don't Know Why?")

In June 2004, before they could record their next song, "Najane Kyun", Strings were approached by the heads at Columbia TriStar Films of India, a sister company to their record label company to include the song in the soundtrack of the Hindi version of the epic Hollywood blockbuster Spider-Man 2.

Soon afterward, they were approached by an Indian director shooting Zinda, a remake of the classic South Korean film Oldboy to do a soundtrack.

For the video, the duo had to act alongside two A-list actors from Bollywood.

It was here that the duo became good friends with John Abraham and Sanjay Dutt and would later appear in more ventures together.
