Vipin Nair of Music Aloud wrote in its review that "the soundtrack had fairly low expectations, but it had thrown up a surprise with a very diverse and engaging set of songs" and gave 3.5 out of 5.[3] A critic from The Humming Heart gave a score 8 out of 10 and said "Mimi may not be a top-shelf Hindi mainstream soundtrack of A. R. Rahman. But, this is a lovely low-key album with tunes that might pay off with revisits in the years to come."[4] Stacey Yount of BollySpice summarised that Rahman "has created an outstanding set of songs for the story and scenes in the film that enhances what is going on onscreen".[5] Sankhayan Ghosh of Film Companion wrote "An album become an extension of its themes, and regardless how the film turns out has a life of its own. Which is not to say that Mimi will bowl you over after a round of casual listening–it doesn't have an outrageously new "sound", an expectation we have come to attach with Rahman with every album of his, major or minor."[6]
Joginder Tuteja of Bollywood Hungama criticised the music as "average and could have been better" but praised the background score as it "enhances the emotions depicted in the film".[7] Jyoti Kanyal of India Today wrote "While the songs complement the storyline and go with the plot, they fail to leave any long-lasting impact."[8]Sukanya Verma of Rediff.com said that Rahman's songs are "filled with soul"; she further stated "Rihaayi De" being similar to "Tu Bin Bataaye" from Rang De Basanti (2006) and "elevates the film's ordinariness to work of depth".[9]
