Input: Question: Before the year 2000, which of the films NikhilVinay's had the highest grossing box office sales? Passage:Nikhil and Vinay are both trained in classical music. Singer Anuradha Paudwal discovered the duo and recommended them to Gulshan Kumar, owner of T-Series music company, and director Chandra Barot, who signed them for the 1991 romantic film Pyar Bhara Dil. The song "Banke Kitab Teri" from the film became popular. The duo then went on to compose music for over 20 films. Their initial successes included Bewafa Sanam (1995), a film which was breakthrough for playback singer Sonu Nigam, English Babu Desi Mem (1996), Uff Yeh Mohabbat (1997) and Papa The Great (2000). The duo composed music for two of Sonu Nigam's successful music albums, Jaan (1999) and Yaad (2001). They went on to score music for Anubhav Sinha's box office success Tum Bin which included hit songs such as "Koi Fariyaad", "Chhoti Choti Raatein" and "Tumhare Siva". Some of their other successful ventures include Hum Tumhare Hain Sanam, Aapko Pehle Bhi Kahin Dekha Hai, Muskaan and Kuch Dil Ne Kaha.
