Yuzo Koshiro/Awesome Music

Check here for more info.

His arguably most famous work is Streets of Rage. Here is the page
His work on the Shinobi games is also top shelf.
Super Adventure Island was released on SNES in 1992. This is what the in-game music sounds like. Let me just repeat that: this is a game that was released in 1992. If the Streets of Rage examples didn't prove that Yuzo Koshiro is a genius, this should.
The Wangan Midnight Maximum Tune soundtracks as a whole, produced by Yuzo Koshiro. This troper, who had played Wangan Midnight R, a game with a more orchestral soundtrack (also by Yuzo Koshiro), before coming to Maximum Tune, was absolutely blown away by "Maximum Acceleration" when he first heard it in Maximum Tune 's first stage.
- "Get You Cornered" from Maximum Tune 3 can make many a racer shiver in fear the first time it's heard.
  - Not to mention the Blackbird's theme from the first game, "Destination Blackout".
Fillmore from Actraiser.
- And this remix of it, which turns it into Crowning Music of Creepy that would not sound out of place in Castlevania.
  - Funny you should mention that... It just so happens he wrote the best clock tower theme in the series.
- Actually let's add Bloodpool from ActRaiser as well.
- Really, everything from Actraiser belongs here. Some of the better examples:
  - Northwall Tree, which is how you know you're in the Very Definitely Final Level.
  - Sacrifices, which is so calming that the player uses it as an item in the game itself to stop a civil war.
  - And the suitably epic final boss music, for your battle with ~~Satan~~ Tanzra.
- Orchestral version of "Sacrifices?" /tear.
He also composed most of Ys I music and collaborated on Ys II. Check out the series page.
He also contributed a song to Dance Dance Revolution Supernova, You Gotta Move It.
If it is any indication, Etrian Odyssey has its own Crowning Music of Awesome page.
This Track, from Kid Icarus Uprising is one of this tropers favorite tracks in the game to put it in quotes:

Viridi: That. Was. AWESOME.//
