Kaatru Veliyidai is the soundtrack album, composed by A. R. Rahman,[4] to the 2017 Indian Tamil romance film of the same name, written and directed by Mani Ratnam[5] starring Karthi[5] and Aditi Rao Hydari.

The trailer, which was unveiled by Mani Ratnam and A. R. Rahman on 9 March, had the unreleased track "Tango Kelaayo"'s bgm and "Jugni" playing in the background.

[1] "Azhagiye", featuring the voices of Arjun Chandy, Haricharan and Jonita Gandhi, and lyrics by Madhan Karky (his second collaboration with Ratnam after Kadal) seems to be a breezy number from A. R. Rahman.

[15][16] The soundtrack album of the Tamil version was released on 20 March 2017 in the presence of actors Suriya and Sivakumar coming as a special guest at the Sathyam Cinemas, Chennai.

[17][18] The soundtrack of the Telugu version was released by Mani Ratnam and A. R. Rahman on 24 March 2017, at a promotional event held in Hyderabad.

"[28] Sify gave the album 4 out of 5 stating "‘Kaatru Veliyidai’ marks the 25th year for AR Rahman in the Tamil music scene.

Fresh effervescence, stamp of authority, signature style, foot tapping numbers, and simple yet experimental tunes – the album ticks most boxes easily.

"[32] 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.

"[34] The Quint commented it as "‘Kaatru Veliyidai’ proves, yet again, that AR Rahman seldom shies away from experimenting with unexplored melodies.

"[35] 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!
