Siddharth K of Sify rated the album 3.75 out of 5 stars, with a verdict: "Yennai Arindhaal is a solid album having tracks in a variety of genres like dubstep, melody, western, fusion, folk, etc. Except his attempt with "Adhaaru Adhaaru", the remaining songs work instantly and would add great value to the movie. Although the longevity of these songs is there to be tested, Harris Jayaraj-Gautham Menon's combination proves once again to be fruitful and shows how Harris can deliver when he works with his favorite director. Yennai Arindhaal is among Harris Jayaraj's better work in recent times"^[33] Vipin Nair of Music Aloud rated the album 7.5 out of 10 saying "Not the best to have come out of the Harris Jayaraj-Gautham Menon combo, but has some musical goodness in offer."^[34]

S. Saraswathi of Rediff.com summarized "Music by Harris Jayaraj [...] do the director proud".^[35] Anupama Subramanian of Deccan Chronicle wrote "Harris Jayaraj’s songs do have a sense of déjà vu of his earlier hits, nevertheless, Gautham has utilized them to take forward the narrative."^[36] Nelson K. Paul of OnManorama wrote "Songs by Harris Jayaraj feel good to the ears; thumbs up for the melodious 'Unakkenna Venum Sollu'. Top-notch background score enhances the mood of the film."^[37] Regarding the song "Unakkenna Venum Sollu", Saritha Rao Rayachoti of Scroll.in stated "The movie sees the return of the partnership of Menon, music composer Harris Jayaraj and lyricist Thamarai. Benny Dayal renders the song with the timbre and tenderness reminiscent of KJ Yesudas and Unni Menon. Mahathi’s voice underscores the constant presence of Hemanika in their lives."^[38]
