Drama Dillagi OST Title Song Video By Ary Digital. Drama Dillagi ost title song is the new version of Nusrat Fateh Ali Khan’s song. The drama lyrics are same “Tumhain dil lagi bhool jani pary gi Mohabbat ki rahun mein aa kar to dekho”, but the is was changed in starching lines like koi hansay to Tumhain gham lagay Hansi na lagy”. The OST is awesome in also in the voice of a new singer. I Hope you will really enjoy this Dillagi OST Title Song video.
