The song comes from 2017 movie "Tiger Zinda Hai" starring Salman Khan & Katrina Kaif. Music by Vishal-shekhar and originally sung by Atif Aslam was most loved song/album of the year. Irshad Kamil has done a wonderful job with the lyrics.
Other song "swag se karenge sabka swagat" was even more popular than "Dil diya Gallan" However both songs became most streamed tracks on YT.
