Arijit Singh hits the initial notes with an absolute power over this rendition and though it turns into a fusion later, there is no intoned confusion at all. Kausar Munir, yet again, does a fine job. Shreya Ghoshal complements the male voice in her systemic perfection, as far as playback is concerned. It is also a suitable number for going out clubbing.[7]

• Rajiv Vijayakar of Bollywood Hungama commented−

Shreya (Ghoshal) is her usual seasoned self in this duet, and Arijit (Singh) imitates Wajid the way Mohit Chauhan did in the earlier tracks, singing in full-throated manner.[8]

• Devesh Sharma of Filmfare commented−

Arijit Singh's and Shreya Ghoshal's voices make it the pick of the album. Melody is the core strength of Sajid–Wajid and the song reminds you of how good they are when they are playing to their strength.[9]

• Joginder Tuteja of Rediff.com commented−

Two of the most in-demand singers, Arijit Singh and Shreya Ghoshal, come together for this winning track from Sajid–Wajid and Kausar Munir. It has a terrific mix of romance, melody and rhythm with a club sound to it.[10]
