OP came into this industry when it was ruled by musically trained badshahs like Naushad Sahab, S D Burmanda etc. Would anybody have given him a chance to make it ? least of all become no.1 MD of his time with a fan following of his own. He, to this day has the greatest number of fan clubs to his name , and all of them are very active. He is simply adored by massess, who do not understand fine nuances of music but would want to listen to something that appeals to their ears. He is a MD who has cds selling on his name even to this day. "OP-collection". "OP hits"..etc. Those times were times of politics in the film music world. And to make the top film makers change their favourites and come to OP for music in itself was a big thing.There was so much competition and if OP could turn away some hot shot film-maker for whatever reasons, it again speaks for his confidence in himself. That he could dictate terms speaks volumes about his popularity with the masses.A person like Guru Dutt dropped SD and made OP compose for AAr Paar, C.I.D,and Mr. and Mrs.55. And GD was suposed to be one of the leading musically elite film-maker.Another musical star was Shammi Kapoor. Amongst all his hits, Kashmir Ki Kali stands out, needless to say, music by OP.It is a fact that films used to sell on his name.Otherwise what is known about Ek musafir, ek haseena and Phir wohi dil laya hoon, Mere sanam?..etc. Aren't the songs of Naya Daur as popular as the film itself?
Even to this day, his songs are played at concerts and are widely applauded.
He is simply evergreen.
