The album received very positive response from critics. Hindustan Times gave the album 4.5 out of 5 stating "The composer has taken us back to the magical ‘90s, where he used to hit the bull’s eye with every given album." Sify gave the album 4 out of 5 stating "‘
Kaatru Veliyidai’ marks the 25th year for AR Rahman in the Tamil music scene. That, invariably means it has been 25 years since Mani & Rahman joined hands for the first time. The duo still has enough gas in them to surprise us and deliver an album that could make us look back and take notice. The best tracks in the album are already popular and that has indeed raised the stakes of the film. Fresh effervescence, stamp of authority, signature style, foot tapping numbers, and simple yet experimental tunes – the album ticks most boxes easily. It is very hard to not like this. And, guess what? The social media is going ballistic." Music Aloud gave the album 3.5 out of 5, stating "Kaatru Veliyidai has some good music, but, as a soundtrack, is not up to ARR-Mani Ratnam standards."
Bollywoodlife gave the album 3.5 out of 5 stating "This is a Mani Ratnam-AR Rahman collaboration. You shouldn't miss it for the world. AR Rahman makes you fall in love again with love and music. There's a song of every kind that will give you a reason to reierate your fandom for the musical maestro." Moviecrow gave the album 3.5 out of 5 stating "Kaatru Veliyidai has the fair mix of melodies and Rahman's experimentations, However, the album is few notches below the usual Rahman- Maniratnam's soundtrack." Deccan Chronicle gave the album 3 out of 5 stating "‘Kaatru Veliyidai’ might not be Rahman's best of works, but it still reiterates his unparalleled, orchestral charm and gives you that Déjà vu, you so often have been craving. At that, it excels, and how!" Milliblog commented it as "In the 25th year of their collaboration, Mani and Rahman prove that the spark is alive and kicking." The Quint commented it as "‘Kaatru Veliyidai’ proves, yet again, that AR Rahman seldom shies away from experimenting with unexplored melodies." Behindwoods gave 3.25 out of 5 to the album and summarised "It's yet another completely avant-garde set of songs high on romance from the master combination of Mani Ratnam and Rahman!" == Awards ==
