A discotheque cum party song, "Khalifa" translates to "leader" in English and the overall lyrical content represents— "The daredevil attitude of today's youth."

Lyricist Amitabh Bhattacharya, producer Dinesh Vijan and director Arif Ali were on board the flight to Chennai.

The word's significance in the religious context dates back to a 1000 years, but it is also used today by the younger generation as a synonym for 'Hey Chief',".

[11] According to Rahman, the hook line of the track "Tu Shining" was inspired from an e-mail sent to him by Danny Boyle post their successes of 127 Hours.

In 2013, when the requirement of a song that began with "Tu Shining", during the recording session for the film the patch tune was approved by Ali.

"[19] At the Indian Express, Suanshu Khurana who assigned the album just one star stated, "A R Rahman fails to recreate magic with Lekar Hum Deewana Dil.

At MusicAloud the soundtrack scores 8 (out of 10), the critic writes, "In a year (2014) that has seen A R Rahman in splendid form, Lekar Hum Deewana Dil is definitely a blip.

"[21] Joginder Tuteja for Rediff gave the album 3 stars out of 5 and mentioned, "Though not memorable, Lekar Hum Deewana Dil can't be dismissed either.

"[30] Sneha May Francis of Emirates 24/7 summarized, "Melodies tuned by music maestro A R Rahman, you can't help but ignore the similarity with Imtiaz’s own Rockstar.

Rahman's score is uneven but dazzles at times – Khalifa works perfectly as the movie's peppy opening number, and if you could look past its bizarre picturisation, Mawwali Qawwali lends the film its most energetic minutes.

[35] Anindita Dev for Zee News wrote, "The music given by the maestro AR Rahman also loses its charm in the plot.

"[38] At Mumbai Mirror, Saumil Gandhi figured out, "There are too many songs with too little diversity in the music on display, a problem that even A R Rahman's score cannot solve.
