upon its july 2015 release, the soundtrack met with critical approval. karthik srinivasan, writing for "the hindu", stated, "composer k has been fairly consistent with his output even as the films they are part of...have been failing consistently. "kirumi's" soundtrack is almost a comeback of sorts for k as he delivers a brilliant collection akin to the sound of santhosh narayanan. topping the soundtrack is "naanal poovaai" that has a curiously ethereal sound (which becomes more evident and interesting in the karaoke version) and k uses the vocal interplay between himself and janani to beautiful effect". musicaloud.com gave a score of 8.5 out of 10 and similarly wrote that the music had "something of a santhosh narayanan/sean roldan type quality to it", but went on to add that it was not "a matter to complain about" and that the soundtrack "definitely ranks among k's top works". the score by k was also received well, with sify writing that "the pulsating background score by k is the biggest strength of the movie; especially the intermission portion is top notch". silverscreen.in wrote that the score was "soulful, and amply enhances the mood of the film".
