A gossipy tidbit from the above-referenced site: "A colossus among song writers, Sahir fought for, and became the first film lyricist to get, royalty from music companies. He would deeply involve himself in the setting of tunes for his songs. Any wonder why they are extra melodious? There was a negative trait too: Sahir would insist he be paid a rupee more for each song than Lata Mangeshkar was.")
