Engeyum Kadhal is dubbed into Telugu as Ninnu Choosthe Love Vasthundi (2012). All Lyrics are written by Vanamali, except "Bathing at Cannes".
The soundtrack received positive reviews from music critics. Indiaglitz mentioned that "Overall, Engeyum Kadhal is one of the best albums of the year. All of the songs bear the Harris stamp and "Engeyum Kadhal" and "Nenjil Nenjil" stand out to be real melodies. " C. Karthik from Behindwoods.com gave a 3/5 rating and said "Overall, Engeyum Kadhal is a breezy, romantic album with a few different sounds and percussions. A few songs bear the typical Harris Jayaraj stamp and the rest are ready to stay in the Top 10 list for a while. We feel that Harris wanted to play it safe, devoid of any experiments, though Bathing in Cannes could appeal as a new genre in Tamil music. The album will definitely appeal to the masses and once the videos go on air, it is certain to make more people inquisitive!" Pavithra Srinivasan of Rediff also gave a 3/5 rating and said "Engeyum Kadhal might sound, at times, like it's a mishmash of Harris Jeyaraj's previous works, but it does have its melodious moments, and those make the album worth a listen."
Rohit Ramachandran of nowrunning.com rated it 2.5/5 stating that "Engeyum Kadhal was marketed as a breezy entertainer. It delivers what it promises.". Pavithra Srinivasan from Rediff gave 2.5 out of 5 stating that "Engeyum Kadhal is one of those movies that promises a lot, but delivers little. Watch the film only if you're in the mood for arm-chair travel to Paris and foot-tapping music". Behindwoods gave 1.5 out of 5 saying that the film was "all glitz, no substance", further adding that "although Prabhu Deva has major supporting features by his side, he has failed to utilize them to the fullest." Sify stated that the film "tries too hard to maintain a tempo, but save for the crackling chemistry and some charming moments involving Ravi and Hansika, the film is just average".
The film had an average opening and the collections in Chennai were ₹2.50 crore after 3 weeks. It was declared an 'average' film by the trade pundits.
