Rafi stood out as Hindi cinema's first prominent playback singer, who dexterously adapted his voice to match with all the leading actors of almost three decades including Bharat Bhushan, Dilip Kumar, Pradeep Kumar, Dev Anand, Rajendra Kumar, Shammi Kapoor, Manoj Kumar, Dharmendra, Sunil Dutt, Jeetendra, Shashi Kapoor, Joy Mukherjee, Rishi Kapoor, etc. Besides becoming heartwarmingly Shammi Kapoor’s voice, his songs like 'Sar jo tera chakraye aur dil dooba jaye' for Johny Walker and 'Hum kale hain to kiya hua dilwale hain' for Mahmood, exemplified his exceptional talent in playback singing. Recorded over 26,000 songs, he sang for all the music composers and lyricists of his time and lent his voice to a wide range of film music genres.
