The series was created by Jun Maeda, so expect a lot of SugarWiki/AwesomeMusic.

* [[https://youtu.be/zIFV8UUs1-c "My Soul, Your Beats!"]], the opening. Note that there are two versions of the song used in the anime. The original features Lia of ''VisualNovel/{{Air}}'' and ''VisualNovel/{{Clannad}}'' fame accompanied by a piano, whereas Episode 4 [[https://youtu.be/0VGoIJ00Pek features]] [=LiSA=] under the in-series rock band Girls Dead Monster. The soundtrack [=CDs=] included not only both versions, but vocal-free versions of each, which has allowed fans to remix it to hell and back -- Lia with rock guitars, [=LiSA=] with piano, and best of all, [[https://youtu.be/Im--kWO229o a remix incorporating vocals and music from all versions]].
* The ending, [[https://youtu.be/xtcvM3s1I1s "Brave Song"]], sung by Aoi Tada. It's always a treat to watch the ending credits while this soft melody plays.
* [[https://youtu.be/Qp3acWyAaA8 "Ichiban no Takaramono"]], the insert song during [[spoiler:Yui's passing]], is a heart-rending mix of heartwarming and tearjerking moments. The lyrics just make it better.
** [[https://youtu.be/YbPTib0eef8 Karuta's version]], played during the last episode's penultimate scene, is even softer on the ears, and just as heartbreaking. [[spoiler:It's hard to refrain from crying as Kanade disappears while Otonashi begs her to stay at his side.]]
** [[https://youtu.be/tm7Xf9818FM Yui's final version]], the fifth and last single released, galvanises the original, forever making it an unforgettable song.
* While Jun Maeda [[WordOFGod said he opted for a minimalist style while composing the soundtrack]], fans are quick to disagree.
** [[https://youtu.be/05qjYHlhOzs "Theme of The SSS"]], which is ExactlyWhatItSaysOnTheTin.
** [[https://youtu.be/uOkOgwAK4XI "Worthy Rival"]], which plays whenever Noda does something awesome.
** [[https://youtu.be/FO5PYEjFN1Y "Critical Point"]].
** [[https://youtu.be/nMuZNH8M2n8 "Decisive Battle"]].
** [[https://youtu.be/GDSpyC6tx0A "Kanade"]]. Just... listen, there's no sufficient way to describe it.
* The in-series rock band Girls Dead Monster (singers alternating between Marina and [=LiSA=], Iwasawa's and Yui's singing voices, respectively) make several songs worthy of praise:
** [[https://youtu.be/sdPwvBJiQJY "Crow Song"]] ([[https://youtu.be/p0WAiVkTrZk Yui ver.]]).
** [[https://youtu.be/8ld4Mj1EkqU "Alchemy"]] ([[https://youtu.be/7ZbUnu8WBn0 Yui ver.]]).
** [[https://youtu.be/aJl2jhDldMs "Thousand Enemies"]].
** [[https://youtu.be/4wD2TKFjV3o "My Song"]] ([[https://youtu.be/QxBvp7AkTdo Yui ver.]]).
** [[https://youtu.be/BqkwTBXtDjo "23:50"]].
** [[https://youtu.be/weBzuwpwAao "Run With Wolves"]].
** [[https://youtu.be/TqQDvfSpRH0 "Morning Dreamer"]].
** [[https://youtu.be/ihsAB1a_1oM "Rain Song"]].
** [[https://youtu.be/_E46HP9yywI "Shine Days"]].
* [[https://youtu.be/xzkYhlIp2Sw "Little Braver"]], [[https://youtu.be/XepU-W76TNk with a PV to boot]]!
* Iwasawa's final single for the series is the aptly named [[https://youtu.be/JIEaA6nB5xQ "Last Song"]].
* "Ichiban no Takaramono" is both this and an epic TearJerker. Both the [[https://youtu.be/Qp3acWyAaA8 Yui-version]] or the [[https://youtu.be/YbPTib0eef8 original]].
* "Theme of SSS" and "Kanade". They're just examples of what the OST offer. Every song in the soundtrack is awesome.
* The ridiculously catchy bassy jig that plays after the credits, as they reveal the next episode. Otherwise known as "[[https://youtu.be/ca7nNviBUGI Let's Operation!]]".
* "[[https://youtu.be/cYv_LV_xNJA Itsumo Hitori~]]".
* For being named after a guy who's name means 'No Sound', "[[https://youtu.be/aGqRyeQTuR0 Otonashi]]" is quite the earful.
