There is music from:

Alien Trilogy, Blue Stinger, Buck Rogers: Countdown to Doomsday, Burn:Cycle, Burning Rangers, Castle of Illusion, Commando, Cool Spot, Dark Savior, Deadly Premonition, DecapAttack, Die Hard Trilogy, Ecco the Dolphin: Defender of the Future, Enemy Zero, Euro 96, Flashback, Fur Fighters, GI Joe, Golden Axe II, (The) Great Giana Sisters, Gynoug, Halo, Headhunter, Jet Set Radio, Jet Set Radio Future, Just Cause 2, Knight Rider, Landstalker, Metropolis Street Racer, Morrowind, NiGHTS, Nomad Soul, Out Run, Panzer Dragoon Saga, Phantasy Star II, Rambo (Ocean loading music with the Morse code), Resident Evil, Rings of Power, Sega Rally 1&2, Shenmue 1&2, Shining Force 3, Skies of Arcadia, Sonic Adventure, Sonic Drift 2, Sonic R, Sonic the Hedgehog 1&2, Sonic the Hedgehog Triple Trouble, Speed Devils, Tails Adventures, Tomb Raider and Urban Chaos (the 3 Jays song).

As you can see, in my opinion there really hasn't been that many games with truly memorable music tracks since Sega's console days. I did also include tracks from Jet Set Radio Future, but that game is from Sega. :) One track from Just Cause 2. That awesome game deserves every recognition it gets. Deadly Premonition has some great music. Morrowind is epic. And Halo is Halo.
