O P the music genius never compromised his class even while composing music for third class films such as Killers, Nasihat(both Dara Singh starrers), CID 909(Feroze Khan starrer), Pran Jaye Par Vachan na Jaye(Sunil Dutt starrer) etc. Though these and some other films flopped, the music was really enjoyable.
A man with abundant self confidence as he was, never caring about his being termed arrogant, he stands tall in our hearts and also his youthful music. Songs of Films Mere Sanam, Phir Wahi Dil Laya Hoon, Ek Musafir Ek Hasina, Kahin Din Kahiin Raat, Dil aur Mohabbath, Aar paar, sone ki chidiya, Raagiini, Thumsa Nahin Dekha, CID, Twelve O Clock, Mr & Mrs.55, Mohabbat Zindagi Hai are even now enjoyable in spite of their being very old.
Even the present day youngsters would like to hum certain songs of this composer. This is evident from the fact that many of OPs songs have been remixed and are in circulation.
