Zubir is estimated to have written about 1,500 songs, including those written for Cathay-Keris Film Productions' Malay films in the 1950s and 1960s. Less than 10% of these songs were recorded. On 22 August 2007, Zubir's family signed an agreement with Universal Music in Malaysia for the latter to manage his works. The copyright in the songs remains with his family. The idea to do so came after his daughter Dr. Rohana met Sandy Monteiro, senior vice-president (Asean) of the Universal Music Publishing Group in 2005 through Monteiro's wife, who was a good friend of hers. Dr. Rohana was reported as saying: "It is time to hand over the songs in order to revive them two decades after my father's passing. I hope to ensure that his songs continue to live in the hearts of young artists in Malaysia."
