Rediff.com wrote that this psychological thriller is an honest effort and a huge relief for movie enthusiasts and gave 3.5/5 stars. Shubhra Gupta of The Indian Express gave the film a rating of 1.5 stars out of 5 and said that, "The plotting and the treatment of My Birthday Song is far too inept to create a solid psychological thriller out of this looping-upon-itself story, whose big reveal is too brief, too late." Sweta Kaushal of Hindustan Times gave the film a rating of 2 stars out of 5 and said that, "Debutante director Samir Soni starts off with an amazing idea which is failed by its execution. It is the heavy-footed treatment of the film that fails it. It is so over-dramatic that even the solid theme on which it is based gets lost."
