Thunder Force II
- The opening, "The Wind Blew All Day Long". Reused again and altered slightly for the title screen of Thunder Force III.
- "Knights of Legend" from Stage 1. X68k Verison. The first part of it is remixed and used in several of the later games as high score themes and menu music.
- "A Ray of Hope", from the 1st side scrolling stage in the Genesis/MD version, or all the slow moving side scrolling stages in the X68k version.
- "EXCEED" from Stage 2.
- "Cruise Control", 2nd side scrolling stage for the Genesis/MD version or the all fast side scrolling stages for the X68k version.
- "Cloud of Dust", 3rd side scrolling stage for the Genesis/MD version, or Stage 3 for the X68k version.
- "Illusion" from Stage 4 (or Stage 5 X68k version).
- "Death's Face", exclusive to the Genesis/MD version as the 4th side scrolling stage music. Resurfaces in Thunder Force AC/Thunder Spirits later as a replacement for one of two TFIII stages.
- The final stage theme, "Irrevocable Dream".
- The ending theme, "Take Off One's Gloves".
Thunder Force III/AC/Spirits
- Thunder Force III's version of "The Wind Blew All Day Long". The title theme.
- "Beyond the Peace", the stage select theme.
- Planet Hydra's "Back to the Fire", and the Spirits version and Best of Thunder Force version.
- Planet Gorgon's "Venus Fire". Likely the only other track that can rival TFIV's "Metal Squad" in series popularity.
- Planet Serien's "The Grubby Dark Blue" and its Spirits version.
- Planet Haides's "Truth" and its Best of Thunder Force version.
- Haides in AC/Spirits is replaced with an entirely new stage and a new track that would later be known as "Omake 2" (see Thunder Force IV).
- The Cerberus stage theme "His Behavior Inspired Us With Distrust".
- "Hunger Made Them Desperate", the Orn Base theme.
- The Final Boss BGM "Be Menaced By Orn", where the series' epic final boss themes began. Also the Spirits version.
Thunder Force IV
The short version is the entire soundtrack qualifies, but highlights are:
- "Lightning Strikes Again", the intro. A kickass way to start the game.
- "Tan Tan Ta Ta Ta Tan", the config screen music. This is actually something of a trademark theme for the series, first appearing in Thunder Force II (as the config music and in a slower variant for the loading screen in the X68k version. As opposed to the brief few seconds you hear it in the Genesis/MD version.) Then later being in TFV and VI.
- "Don't Go Off", the stage select theme.
- "Fighting Back", Stage 1A, and its Best of Thunder Force version.
- "Evil Destroyer", Stage 1 boss. Arranged on the OST album as ''"Remained Revolution", which combines it with "Lightning Strikes Again" for maximum rocking.
- "Space Walk", Stage 2A.
- "Attack Sharply", Stage 2 boss.
- "The Sky Line", Stage 3A.
- "Simmer Down", Stage 3 boss.
- "Sand Hell", Stage 4A.
- "Strike Out", Stage 4 boss.
- The appropriately named "Battle Ship" for Stage 5, as well as its Best of Thunder Force version.
- "Stranger", Stage 5 boss
- "Neo Weapon", the Mid-Season Upgrade theme.
- "Great Sea Power", Stage 6.
- "Sea of Flames", Stage 7.
- "Metal Squad", Stage 8. A huge fan favorite and arguably the most popular track in the series. If someone names their favorite song in the game, it's probably going to be this one.
- "Down Right Attack", Stage 9.
- "War Like Requiem", the final boss theme. Which takes the epic final battle theme motif established in TFIII, and multiplies it by a factor of kickass.
- The ending themes: "Shooting Stars" for Easy, "Silvery Light of the Moon" for Normal, "Light of Silence" for Hard, and "Love Dream" for Maniac.
- "Stand Up Against Myself", the staff roll theme. Yet another fan favorite. And the fuller arrangement from the OST.
- This remix of "Lightning Strikes Again" and "Metal Squad" mashed together into one hell of a mind-blowing metal song. Holy shit.
After you beat the game, you unlock several Omake tracks to listen to in the config menu:
- Omake 2, which is originally from Thunder Force AC/Spirits.
- Omake 3.
- Omake 4.
- Omake 5.
- Omake 8.
- Omake 9.
Thunder Force V
- "Beginning of War", the opening.
- "Attack Point", the stage select theme.
- "Legendary Wings", Stage 1. Another popular track that features a clever callback to "Back to the Fire" from TFIII.
- "Beast Jungle", Stage 2.
- "Rising Blue Lightning", Stage 3, and "Reffi's Mix", arrange from the official soundtrack.
- "Cyber Cave", Stage 4. Also "Cyber Cave Hi-Mix" and "Cyber Cave -Sunset Clouds", from Broken Thunder -Project Thunder Force VI-.
- "Steel of Destiny"'', Stage 5. A blood-pumping track that plays as you fly through space in the Brigadine and blow away an entire space fleet.
- "Ishtar Edge ReMix", arrange from the official soundtrack.
- Long Version variant.
- "Steel of Destiny -Cry Sky", from Broken Thunder -Project Thunder Force VI-. A piano version of the song.
- "Steel of Destiny -Take Off-", from Broken Thunder -Project Thunder Force VI-. The ultimate version of the song that incorporates live guitars. The result is amazing.
- "Guardian's Knight", the Stage 4 boss theme. An appropriate tune for the High-Speed Battle between you and the giant mecha defending the Tower of Babel.
- "Duel of Top", the Stage 5 boss theme. Basically, a more sinister remix of "Lightning Strikes Again" from TFIV. Very fitting considering what the boss is.
- "The Justice Ray Part 2", continuing the tradition of epic last boss themes.
- "Last Letter". After hearing a game full of energetic synth rock, in contrast, a beautiful, yet melancholy piano melody is presented for the ending theme. Fail to beat the last boss before it escapes, and "Please Seal it Up!" plays instead.
- "Record of Flight", one of the high score themes that remixes "Hunger Made Them Desperate" from TFIII. It is played if you get the top score on your save file.
Thunder Force VI
In this installment, the musicians closely associated Thunder Force, Tomoni Otani (II/III), Toshiharu Yamanishi (III/IV/Broken Thunder), Takeshi Yoshida (IV), and Hyakutaro Tsukumo (V/Broken Thunder), are replaced by Tayamo Kawamoto of RAY Series fame, Go Sato, known for the Raiden series, Motoaki Furukawa known for his Gradius/Konami works, and Tsuyoshi Kaneko, composer of Segagaga and other Sega works. Due to this, the music is a bit of a departure from the usual Thunder Force fare, but still has some good tunes and rocking tracks.
- "Course Select Music", which seems to call back to "Don't Go Off" from TFIV.
- "Ruined Green" 1-A and 1-B for Stage 1.
- "Gargoyle Perfect", Stage 1 boss.
- "Flame Maiden", Stage 2 boss.
- "Ever Blue" 1-A and 1-B for Stage 3.
- "Cherub Purple", Stage 3 boss.
- "B3", Stage 4 boss.
- "Cerberus 2", for Stage 5-A.
- "Full Speed", for Stage 5-B.
- "KIN3-COOL", the "A" alternate for ORN-Faust encounters. A remix of "Cool's Theme" from Segagaga.
- "KIN3-CERB", the "B" alternate for ORN-Faust encounters. A remix of "His Behavior Inspired Us With Distrust" from TFIII.
- The Stage 5 boss features "Orn Styx", "Orn Rynex" and "Orn Gauntlet" which are remixed versions of title themes from the three previous games ("The Wind Blew All Day Long" for Styx, "Lightning Strikes Again" for Rynex, and "Beginning of War" for Gauntlet), as you fight super-sized versions of the highlighted ships for those games.
- "Orn Emperor", the last boss theme. Part 1 and Part 2.
The end product of this turned out unfortunate, but it features some music that was originally meant to be used in TFVI before its Development Hell period. It is awesome:
- "BT", Hyakutaro Tsukumo's version of the opening.
- "BT OP Ver.Yamanishi", Toshiharu Yamanishi's version of the opening.
- "Fire-Leo 05P 'SYRINX'" alt, Stage 1, and its Arranged version.
- "Arc Angel" alt, Boss theme.
- "Full Metal Goddess" alt, Stage 2, and its Arranged version.
- "Moon of Black Rain 'BG-00P'". alt, Stage 3.
- "Moon of Mind" alt, Stage 4
- "Broken Thunder 'CODE-RVR-03G' -Sword Breaker-" alt, Stage 5. The main theme.
- "The Justice Ray Part 3" alt, The last boss theme. Fun fact: after TFVI was initially canceled, it was used in the Simulation/RPG game Segagaga as the boss theme for the Thunder Force inspired side scrolling segment at the end of the game.
- The Ranking music and its Arranged version.
