History AwesomeMusic / ACertainMagicalIndex

* For the ''Literature/ACertainMagicalIndex'' TV Songs Album, the singers of the openings and season 2 endings (Music/MamiKawada and Music/MaonKurosaki respectively) got together for a duet called [[https://youtu.be/w_o6cjFxrXE "Snap out of it!!"]]. Needless to say, it makes a perfect addition to the series fantastic music catalogue.

Being a long-running LightNovel with a popular SpinOff, both of which have currently two seasons of animated adaptation each, ''LightNovel/ACertainMagicalIndex'' (as well as ''Manga/ACertainScientificRailgun'') brings a great deal of songs to the table, and all of them are [[SugarWiki/AwesomeMusic awe-inspiring]].

* For the ''LightNovel/ACertainMagicalIndex'' TV Songs Album, the singers of the openings and season 2 endings (Music/MamiKawada and Music/MaonKurosaki respectively) got together for a duet called [[https://youtu.be/w_o6cjFxrXE "Snap out of it!!"]]. Needless to say, it makes a perfect addition to the series fantastic music catalogue.

* All four openings ([[https://www.youtube.com/watch?v=54hNMot2H4E "PSI-missing"]], [[https://www.youtube.com/watch?v=rAOx5dmTBgs "masterpiece"]], [[https://www.youtube.com/watch?v=JKBgncvXx0c "No buts!"]] and [[https://www.youtube.com/watch?v=4EMhgk8beT0 "See visionS"]]) have a techno vibe and electronic synth that perfectly captures Academy City as a state of the art future city, as well as capturing the hectic life style that Touma constantly finds himself in.
* Index's ThemeMusicPowerUp, [[https://www.youtube.com/watch?v=QPlL4P5Cz4E "jellyfish"]], first plays when Index faces Sherry Cromwell's golem, with the entire song starting off rather slow before throwing more instruments that immediately pick up the speed of the song while also occasionally throwing in brief spurts of lyric here and there that briefly slow the song down a little before picking right back up, all leading to an ebb and flow just like a jellyfish drifting in the water.
* Episode 12 of ''Index'' Season 1, where Touma confronts Misaka who is planning to throw her life away to save the Sisters before he convinces her not to, gives us the insert song [[https://www.youtube.com/watch?v=LCHGR4_XG6Y "Ame"]], with lyrics about how Touma will always be ready to reach out a hand to any one in need.
* [[https://www.youtube.com/watch?v=9ArZVKo7EcA "King of Witch Hunters (Majou Kari no Ou)"]] is a hauntingly scary song that plays after Aureolus Izzard first cuts off Touma's arm.
* [[https://www.youtube.com/watch?v=fLzWzpMdS64 "Overdrive"]] is the first theme that plays in ''Index'', and its electric and reverse bass clue you in that this is going to take place in a super advanced city with all sorts of robots and powers being thrown around.
* [[https://www.youtube.com/watch?v=pKXaEYHnVVc "Turnabout (Gyakuten)"]] plays when Touma and Accelerator first battle. Its slightly upbeat rhythm shows that Touma has the power to take down the number 1 esper in Academy City, but it also has a rather intense beat that signifies that Accelerator is going to make Touma work for his victory.
* Touma's themes, [[https://www.youtube.com/watch?v=Qx6YL1ld0iY "Imagine Breaker (Gensou Goroshii)"]] and [[https://www.youtube.com/watch?v=-Ofmj4ouopc "Breakthrough"]], signify that who ever he's facing is about to have their plans destroyed and a fist to their face.
* The second season has some downright brutal battle theme songs: [[https://www.youtube.com/watch?v=Wz8iXVp2vGM "Greater Power (Kyoudai no Chikara)"]], [[https://www.youtube.com/watch?v=PemRTNwCo0Y "Scheme (Sakubou)"]] and [[https://www.youtube.com/watch?v=5D7Kj5qHbzU "A Shadow Draws Near (Semaru Kage)"]], which also doubles as Accelerator's new theme song. Who says anime fights and trance music can't go well together?!
* The second OST gives us [[https://www.youtube.com/watch?v=mZOQXqmZzKE "New Fight (Arata Naru Tatakai)"]], [[https://www.youtube.com/watch?v=1nU3sFT8ths "Large-scale Magic (Dai Majutsu)"]] and [[https://www.youtube.com/watch?v=prb2c1AnzVU "The Queen's Fleet (Joou Kantai)"]]. Also, [[https://www.youtube.com/watch?v=TUJ1CZR0e-Y "Hymn (Seika)"]] supplies our daily dose of SoundtrackDissonance when [[spoiler: Accelerator awakens and punches Kihara so hard the man '''[[SugarWiki/MomentOfAwesome burns up in the fucking atmosphere while flying away]]''']].

%%* The theme song to TheMovie, [[https://www.youtube.com/watch?v=eVeFToEuZd4 "FIXED STAR"]].

** [[https://www.youtube.com/watch?v=OLfA1GhW97c "Electric Chase"]] is the perfect theme song of Mikoto's {{tsundere}} side, so much so that it was reused in the second season of ''Index''!

** The 1st OP, [[https://www.youtube.com/watch?v=UmnQ2fEoXUI "only my railgun",]] showcases protagonist Mikoto Misaka's character with a fast tempo matching her quick temper, and electronic beats matching her powers (ShockAndAwe).
** The second opening, [[https://www.youtube.com/watch?v=57X3uq9s33U "LEVEL5-judgelight]], kept what was good with the first opening and added a different set of lyrics, showing Mikoto's firm resolve in becoming a hero.
%%** From the OVA, we got [[https://www.youtube.com/watch?v=m9yOgj567kc "future gazer"]] while from the video game we got [[https://soundcloud.com/aki-wong/01-way-to-answer "way to answer"]].

%%** The soundtrack used in ''Railgun'' is just as amazing as the music used in ''Index''. You have [[https://www.youtube.com/watch?v=Nw8oFkORyjU "Tokiwadai Junior High (Tokiwadai Chuugakkou)"]], [[https://www.youtube.com/watch?v=JOxdNM-NfUs "This is Judgement! (Judgement desu no!)"]], [[https://www.youtube.com/watch?v=Rl9hZoTQj08 "battle area"]], [[https://www.youtube.com/watch?v=qsfRmlrIBPk "Tokiwadai Dormitory (Tokiwadai Joshiryou)"]], [[https://www.youtube.com/watch?v=ZLkFFkn3TCI "high speed"]], and [[https://www.youtube.com/watch?v=MWZaYM0cLZQ "Evening at Academy City (Gakuen Toshi no Yuugure)"]].
%%* ''[[TheMovie The Miracle of Endymion]]'' adds more to the list, especially the insert songs from Arisa Meigo (singer: Creator/SachikaMisawa): [[https://www.youtube.com/watch?v=IeqFAJ-AiXs "Telepath ~Hikari no Tou~"]], [[https://www.youtube.com/watch?v=8GTnGx8NqFc "ATARIMAE no Kyori"]], [[https://www.youtube.com/watch?v=trgAXuDK7J8 "Brand New Bright Step"]], [[https://www.youtube.com/watch?v=e0elZ_WwKmQ "Gloria"]], [[https://www.youtube.com/watch?v=PRYvIT9X39Y "Ashita, Hareru Kana"]], and [[https://www.youtube.com/watch?v=OgDcI-KVpl0 "OVER"]] (topped by a [[https://www.youtube.com/watch?v=TZtC0YvgQFU duet]] with Creator/YokoHikasa at the movie's climax). The score itself reintroduces familiar re-arranges of [[https://www.youtube.com/watch?v=RMMh2ycK8-Q "Hey, Touma!"]] and [[https://www.youtube.com/watch?v=vKXBzs6ugBE "Tokiwadai Dormitory"]] while mixing them with newer tracks such as [[https://www.youtube.com/watch?v=aD5kVqLG0KQ "What that bastard did!"]] and [[https://www.youtube.com/watch?v=VxtptVgtnqA "Those cursed by magic"]].
* ''Manga/ACertainScientificAccelerator''[='=]s opening theme, [[https://www.youtube.com/watch?v=OplYMNAv0LA "Shadow is the Light"]], is the perfect theme music for the Strongest Esper, and ditches the usual synthpop sounds from the other openings for a heavier IndustrialMetal sound with lyrics that perfectly encapsulate Accelerator's journey from villain to hero.
* For the ''LightNovel/ACertainMagicalIndex'' TV Songs Album, the singers of the openings and season 2 endings (Music/MamiKawada and Music/MaonKurosaki respectively) got together for a duet called [[https://www.youtube.com/watch?v=w_o6cjFxrXE "Snap out of it!!"]].

* Index's ThemeMusicPowerUp, [[https://www.youtube.com/watch?v=QPlL4P5Cz4E "jellyfish"]], it first plays when Index faces Sherry Cromwell's golem, with the entire song starting of rather slow before throwing more instruments that immediately picks up the speed of the song while also occasionally throwing in brief sports of lyric here and there that briefly slows the song down a little before picking right back up. Leading to an ebb and flow just like a jellyfish drifting in the water.
* Episode 12 of Index Season 1 gave us a very nice insert song called [[https://www.youtube.com/watch?v=LCHGR4_XG6Y "Ame"]]. Which is the episode where Touma confronts Misaka who is planning to throw her life way to save the Sister's before he convinces her not too. With the lyrics being about touma and how no matter what he'll always be ready to reach out a hand to any one in need.
* [[https://www.youtube.com/watch?v=9ArZVKo7EcA "King of Witch Hunters (Majou Kari no Ou)"]], is hauntingly scary song that plays after Aureolus Izzard first cuts off Touma's arm.
