Awesome Music / Komi Can't Communicate

• The opening song for the anime, Cidergirl's "Cinderella", functions as an Expository Theme Tune about Tadano noticing Komi's loneliness and suggesting they take a moment to enjoy the simpler things of life. It also hints towards Tadano's growing feelings for Komi despite him trying to deny them.
• The ending of the first episode, "Sympathy" by Kitri, is a melancholic but intriguing tune that sets the mood for, as its lyrics state, some summer drama. While the series' proper ending, "Hikare Inochi" also by Kitri, has its own value, many lament that the first wasn't used for the rest of the run.
• The OST that plays during the memorable chalkboard scene. Without a single word, it fully conveys Komi's wish of making 100 friends and hits an amazing high the further she and Tadano write. In other words, the OST represents Komi: in the beginning, she was alone and quiet and becomes more hopeful once Tadano becomes her first friend.
