music career started at the age of fifteen; she met film director Feroz Khan at a party in the United Kingdom, who later requested that she audition with Biddu, a London-based Indian music composer, for his film Qurbani. Biddu then signed her up for "Aap Jaisa Koi", a song he composed for the film. The song turned to be a huge success in India, and Hassan quickly gained recognition and acclaim. In 1981, Hassan won the Filmfare Award for Best Female Playback for the song, becoming the youngest to win at age 15 as well as being the first Pakistani to win the award. Hassan promptly collaborated with Biddu on numerous other projects; in 1981, she became the first playback singer to release an album. Her first album was Disco Deewane. The album broke sales records in Pakistan and India and even topped the charts in the West Indies, Latin America and Russia, becoming an international success. The album became a mega-hit and Hassan became an established pop singer in Pakistan; the album also featured vocals by her brother Zohaib Hassan. Nazia and Zoheb were signed by EMI Group and were the first South Asian singers to be signed by an international music company. At the height of Disco Deewane fever, she frequently drew large crowds, such as 50,000 to 100,000 people greeting her at Calcutta Airport. After the release of Disco Deewane, Biddu offered Zoheb and her a chance to act in the movie Star in 1982, but they refused and instead chose to perform the soundtrack. The soundtrack album, Star/Boom Boom, was released. She was nominated for the Filmfare Award for Best Female Playback Singer, although this time she did not win. The album was successful and increased the popularity of Hassan and Zohaib in Pakistan and India. Hassan's third album, Young Tarang, was released in 1984. It was the first album in Pakistan to feature music videos, which were made in London by David Rose and Kathy Rose. The album became one of the most popular in Asia. "Ankhien Milane Wale" was a popular song from the album. After the release of Young Tarang, she returned to singing for Bollywood movies as a playback singer. Her fourth album, Hotline was released in 1987. Aa Haan was the most popular song of the album. In 1988, she and her brother Zohaib appeared with music maestro Sohail Rana in
