Mortal Kombat (1992) as a whole has some pretty good tunes, but the Genesis port remixed almost all of the music to fit the Genesis' sound chip. And it did so damn fine, courtesy of expert Genesis composer Matt Furniss. To give an example, here's his take on the game's main menu theme. His themes are so beloved by fans that some consider his arrangements better than even Dan Forden's original versions. The music in the Genesis port of the Mortal Kombat II was also composed by him (here's the Dead Pool theme from that version).
Mortal Kombat: Deadly Alliance has a dark, intense and atmospheric soundtrack that perfectly matched with the franchise's resurrection in the 2000s, courtesy of Dan Forden, Rich Carle and Vince Pontarelli.
"Lost Tomb" is one of the game's standout tracks, with a threatening techno beat and percussion mixed with creepy synth patterns.
"Kuatan Palace" uses a slow-paced, incredibly eerie electronic track that evokes a truly evil vibe. Possibly one of the darkest tracks in the entire series.
"Lava Shrine" has an energetic, old-school 90s rave theme that will remind fans of the movies.
Mortal Kombat: Deception continues the dark and threatening style of Deadly Alliance's sound, albeit without Dan Forden working on the music. That being said, the soundtrack still stands on its own while retaining the series' spirit.
"The character select music". A hip-hop beat mixed with industrial rock that fits the game well and gets you pumped for a fight.
"The Portal" sees an update to the original early 90s sound of Mortal Kombat 2 that lends to the stage's atmosphere.
The trailer for Geras' reveal uses a brutal instrumental version of "Decimator" by All Good Things.
The launch trailer has a pretty impressive remix of the classic "Mortal Kombat" theme.
The Tournament stage in the game itself uses a different, but no less kickass version of the "Techno Syndrome".
For the stage music themselves, a lot of fans particularly like the somber "Shang Tsung's Island Ruins" and the trap-meets-metal of "Black Dragon Fight Club".
Shao Kahn's trailer uses the balls-crushingly awesome "Soul Crusher" by Liquid Cinema.
"Rise" plays during the start of the credits. Listen closely, and you'll realize it's a remix of the song used in the debut trailer. Coming off Story Mode's ending, it truly does feel make you feel like you've witnessed the end of an era.
"The Teahouse (Day)" pays homage to the first two games of the series by incorporating their motifs and mixing them with a variety of strings and percussion for an authentic Eastern feel. The Night variation has a more intense sound, with added plucked strings and sounds of bells ringing to show that this teahouse is a place of battle, no matter the time of day.
"Tarkatan Colony" is an excellent mix of intense and mysterious, with its mix of heavy, pounding percussion and tribal horns in the first round, a perfect fit for the brutality of the Tarkatans. The subsequent round's music makes the tribal influence even more prominent by ramping up the tempo and adding some strings for an even more intense track.
"Cage Mansion" brings back the techno feel of the 3D Midway era and intermixes it with '80s-style motifs, with heavy synths and pulsing beats, perfectly fitting the showboating personality of Johnny Cage.
Mortal Kombat Mythologies: Sub-Zero: Quan Chi's boss theme is an intense, threatening tune, Shinnok's subsequent fight having a track that is somehow both ethereal and groovy, until it kicks into high gear during the Beast/Corrupted Shinnok phase, as short (and difficult) as it is.
Mortal Kombat: Special Forces is divisive, but its intro has an awesome spy feel to it. It could shine brighter in a different game, though...
Mortal Kombat: Conquest: Whatever else one can say about this show's quality in terms of writing and acting, there is no denying that it more than lived up to the franchise's reputation for great use of electronic rock. Special mention goes to the theme used in the fight between Kung Lao and Shang Tsung in the pilot episode and the track from the episode in which Reptile fights a member of his race. And of course, the theme song is suitably blood pumping for an action show.
