The Kamen Rider franchise has a wealth of awesome music, beginning with the original series' opening theme "Let's Go Rider Kick" to show the valour and strength of this new hero in a true '70s rock with orchestra.
Alive A Life by Rica Matsumoto the opening theme of this series. has a very well made soundtrack for the series. While the music itself is awesome, the "glass break" sound effect in the opening episodes makes it even better. Completely suitable for a show about masked heroes (and villains) fighting each other inside the Mirror World.
The first ending Hatenaki Inochi by Hiroshi Kitadani, debuting alongside Shinji's first official transformation into Ryuki, it again says everything about Shinji while sounding badass at the same time.
The second ending Revolution, also know as the Survive Form theme, is probably one of the most Hot-Blooded songs in the franchise (also sung by "Kitadani Hiroshi", no less). It starts with a slow, gentle piano progression before picking up some pace and finally going into full throttle high-energy once the chorus begins. Iteven encompasses everything about Shinji's character in the second half of the series in its first verse, and everything about Ren in its second verse. Its debut alongside Shinji's Survive Form, with Shinji activating Survive for the first time and declaring that he definitely wouldn't die so Ren wouldn't become a killer, made the song and the scene one of the most iconic of the series and possibly the franchise.
The opening, Justifaiz, is a great song that fits with the show's darker theme. In 2017, the show's lead actor Kento Handa made a remixed cover of the song's first verse. The arrangement better fits the depressing feel of the show as Kento/Takumi walks through a bunch of the show's filming locations, ending with finding himself still lying on the hill where the show ended.
"Round Zero~BLADE BRAVE" by Nanase Aikawa, the first opening, is a rousing pop-tech tune that illustrates the Riders, especially when the opening sequence has the main cast in flashy, formal suits and slight dancing.
"Kakusei" by Rider Chips emphasizes whenever Blade fights and succesfully defeats any Undead.
"Rebirth", sung by Kousei Amano (Tachibana's actor), embodies even more of Blade's epicness (especially when he's in Jack Form) and, by extension, Garren himself.
"ELEMENTS", the second opening and also by Rider Chips, is an epic rock track with the accompanying opening sequence having more dramatic and edgier scenes (such as Blade punching at the screen and shattering it).
"Take it a try", sung by Ryoji Morimoto (Hajime's actor), showcases both Blade King Form whenever he triumphs in battle against his opponents as well as Kenzaki's increasing bond with Hajime.
The first opening, Kagayaki, is a heroic theme that combines all of the instruments that the heroes use in the show, also being very notable for being the only opening song in the entire franchise without any singer.
Kamen Rider Den-O's "Climax Jump" is a thrilling anime-esque tune to hype up folks for Ryotaro's adventures to maintain the sanctity of the timeline with his friends from the Shinkansen of time DenLiner and a few more allies riding their own train while also doing his climax jump to live his life to the fullest. Also available in Imagin flavor which mingles the DenLiner's resident Imagins to give a fun take of the song in their own vocals. And the many remixes of "Double Action".
Kamen Rider Kiva had a ton of awesome tracks during its series' run, most if not all of which were sung by the actors themselves. Then, June this year, Toei released a reunion album featuring redone versions of some of the previous songs. The fact that this happened at all makes it even more awesome, as it's probably the first time it's happened to any Rider series thatisn'tDen-O.
Gackt's "Journey Through the Decade", the opening theme, which is a hard rock tune that illustrates Decade's journeys throughout other worlds and such.
Decade's theme, "Ride the Wind", shows Tsukasa being epic in battle as well as his bonds with some of the AR characters he met.
Decade's transformation theme. This is a kick-action number sporting an acoustic guitar and small references to latin music with its claves and percussion. It perfectly showcases Decade's sheer power and edge as the Destroyer of Worlds who's also trying to save his own world.
Diend's theme, "Treasure Sniper", illustrates the increasing growth between Tsukasa and Daiki.
The almost bittersweet "Journey Through the DECADE ~ Re-Mix RIDE 'Symphony'" is a melancholic symphonic version of the season's theme song, which is more than enough to start anyone's waterworks during the show's sombre moments. It even plays again when Tsukasa Kadoya sadly passes on at the end of Rider Time: Kamen Rider Zi-O vs Decade.
The ridiculously catchy and equally brilliant "Switch On!" by Anna Tsuchiya, being quite the rousing piece that's entirely appropriate for living in the exciting school days of Fourze.
"TAKE A STEP FORWARD!" Whenever "Giant Step" starts playing, you know awesomeness will ensue. Additionally, May'n later released a solo version of the song which isn't quite as energetic as the original, but more than makes up for it with her trademark powerful vocals.
Shooting Star by everset, the theme for Kamen Rider Meteor, having the epic rock music that showcases Meteor's epicness. The PV takes it even further by simply being Meteor beating up 100 Dustards.
"Bounce Back", Magnet States' theme, is an awesome tune to represent how Gentaro gets back on track despite taking blows.
The finale of Swan Lake playing over the rematch between Meteor and the Cygnus Zodiarts. You don't get many Rider Kicks to classical music, but damn if it didn't work wonders.
"Evolvin Storm", the theme of Meteor Storm, is quite the treat, with the PV in particular being a mixture of awesome, and silly.
"COSMIC MIND" , the theme for Cosmic States, is very befitting of the main Rider's final form. "SHOW ME YOUR COSMIC MIND!" indeed.
"Endless Play" brings the edge to fight scenes, perfectly encapsulated during the finale's Bike Fu sequence.
Rider Zu No Tairitsu plays when Gaim uses Kiwami Arms for the first time. It truly sounds like a war deity has entered to end the battle.
Another by Rider Girls, Toki no Hana (Flower of Time), the theme of the Jimber Arms, heard during the Gaim/Bravo fight in #17, summing up the sheer power of that new power and Gaim's will to save everyone in a fast, fleeting rock tune.
Has a wonderful opening song in "Be The One" by PANDORA feat. Berverly. The techno music made by PANDORA and Beverly's AMAZING singing voice combined create a catchy song that shows the ideas of determination and hope that are present in the the series.
"Build Up" for Build's Genius form is a rocking tune dripping with pure genius and heroism, a fitting description of that Sento's strongest Rider form yet.
"CROSS" from the V-Cinema of Cross-Z, is a rock ballad detailing the changes that Banjo has gone through and the need to Enemy Mine with Evolt to use Cross-Z Evol.
"Perfect Triumph", from the V-Cinema of Grease, an energetic rock beat that shows off Kazumi's Determinator status to protect his friends and finish off the last villain that marks the end of Build's saga.
The opening, "Over 'Quartzer'" by Shuta Sueyoshi feat. ISSA, is a catchy electronic theme that is sung by the two singers who did the openings for Faiz and Den-O.
Zi-O's Image Song, "Zi-O! King of Time!", is sung by So Okuno himself. It plays in #16 when Sougo once again decides to become king and #22 when Zi-O II debuts.
The opening for Rider Time Shinobi, "IZANAGI", is sung by Hideya Tawada and perfectly captures the ninja theme of the rider.
The opening for Rider Time Ryuki, Go! Now! ～Alive A life neeo～ is sung by the original singer for "Alive A life", Rica Matsumoto, and it's every bit as awesome as the first one.
"Believe Yourself", from the Kamen Rider Agito OST, plays in Zi-O #32 during the Zi-O Trinity and Agito Trinity team up fight, and it proves it is still one of the best ending themes in the franchise's history.
"Kagayaki", the first opening from Kamen Rider Hibiki, plays in #34 during Kiriya's debut fight as Hibiki. It seems that from now on, the theme music of past seasons will be returning!
Woz's Image Song for both Black and White counterparts, "Black & White", sung by the actor Keisuke Watanabe, plays in episodes 37 and 38 showing off WozGinga Wakusei and Taiyo forms for each respective episodes.
Kamen Rider Grand Zi-O's image song, "Next New Wφrld" by RIDER CHIPS, plays during the form's debut, and takes what was already an Awesome Moment and makes it even better.
The jingle that plays during Grand Zi-O's henshin may go on for a almost a minute, but those minutes are spent with a catchy tune which somehow manages to make lyrics just listing the different Kamen Riders that came before Zi-O amazing.
The theme to Zi-O vs. Decade and Decade vs. Zi-O, "Inside Out", sung by both Masahiro Inoue and So Okuno, has two versions for each series, channeling the score for the respective seasons.
"Aruto's Determination" begins solemnly and introspectively, but quickly moves into a rising melody and culminates in a series of powerful guitar riffs, demonstrating our hero gathering his resolution and stepping into the fray.
The REAL×TIME movie gives us "Zero-One & Zero-Two REAL×TIME Suite", the theme of Zero-One and Zero-Two. It begins peacefully and emotionally before quickly evolving into an exciting and badass remix of the original Zero One theme.
Both the OP and ED themes are very catchy and energetic, courtesy of the legendary Japanese ska band, Tokyo Ska Paradise Orchestra.
"ALMIGHTY ~ Kamen No Yakusoku" features a catchy brass section accompanied by a energetic guitar riff and bouncy percussion, tied off by some absolutely wonderful vocals by [Alexandros]'s Yohei Kawakami.
"Kamen Rider Saber" is a brassy, confident tune accompanied by a fun dance that is sure to get you moving.
"Taju Rokou", the theme song to The Phoenix Swordsman and the Book of Ruin, is quite the wonderful and classic jazz number to listen and jam to.
Combining J-pop dance and vocal group Da-iCE, of One Piece fame, with Vice's voice actor Subaru Kimura makes for an extremely addicting liveDevil that, while it strays away from typical Rider openings, does so without foregoing the theme of Revice making it a fitting theme in the series.
"Without You", the ending theme of Kamen Rider Revice: The Mystery, lets Junya Komatsu's (Hiromi) and Kentaro Maeda's (Ikki) voices shine against a beautiful pop-rock instrumental. The DEAR GAGA version is just as potent - maybe even more so - as Junya Komatsu sings alone with a powerful orchestra.
Kamen Rider Vail's leitmotif is a terrifying but epic track complete with a blaring drone akin to Prowler's theme.
"MY DREAM", the ending theme of Revice Legacy, is a beautiful duet sung by Yukimi's actresses Kurara Emi and Sakurako Okubo.
"Mirage Mirror" is Live's ending theme, being a duet between Daiji and Kagero. While it's traditional for an endgame Kamen Rider song to be a duet (or a trio), there's a meta twist that the two of them are played by the same actor.
#46 gives us "Cherry-ish", the theme for Invincible Jeanne form, sung by Ayaka Imoto and Miku Itou is just pure awesome, going from fun pop-rock to surprisingly hardcore rock in a heartbeat.
"George Karizaki no Rider System", sung by Noritaka Hamao in-character, is essentially Kamen Rider's answer to Super SentaiHero Getter, featuring all the Rider series from 1971 to the present day.
"Riot in bloom", the ending theme from the Girls Remix. spin-off is a fast-paced song that shows Hana Natsuki's growth from her time as Aguilera. Yui Asakura really gets to show off here.
Kamen Rider Geats: Shonan no Kaze return from their tenure under Gaim, and this time, are in collaboration with Koda Kumi for the opening theme. The result is "Trust・Last", a rock piece that fits the show's theme of high stakes.
