Video Games/Awesome Music/Arcade Only

On the pinball side of things, 1989's Black Knight 2000 and 1993's Twilight Zone were known for having one of the best soundtracks ever for a pinball game. The latter game uses Golden Earring's 1982 hit song, "Twilight Zone" as its main theme.
And what about Out Run? As legendary as the game itself, are the songs Magical Sound Shower, Passing Breeze, Splash Wave and even the Game Over theme (Last Wave). These are the only songs in the game, so it's all the more impressive that they deserve recognition on this page.
The same can be said of Super Hang-On. It had four great songs: Outride a Crisis, Sprinter, Winning Run and Victory Road.
Gyruss (in its initial arcade form) only has one recurring song, a remix of Bach's Toccata and Fugue in D minor, but hearing the song in stereo sound on an '80s (!) -era arcade machine will make you say "Whoa!"
For a game about murdering other assassins to jammin' jazz tunes, the ending theme to The Outfoxies, Enjoy Life is as chilled and lovely a piece of jazzy piano as you'll ever find.
Allen Snider's theme in Fighting Layer. Sweet Jesus, is it stellar.
X-X-X-X-MEN
Phantom of Blue from Wangan Midnight Maximum Tune 3 is an AWESOME techno/trance song.
The first world theme from Neo Bomberman.
Daddy Mulk from The Ninja Warriors. Awesome song that has been remixed many times, it's a shame the (equally awesome) remake didn't have a remix of it.
