When asked about my favorite game music, invariably my answer is always the entire 92-track masterpiece that is the Ace Combat 5: The Unsung War soundtrack.
A sampler:
Ace Combat 5 Track 55/92: The Unsung War (as @Bobop4 posted)
Ace Combat 5 Track 50/92: Grabacr
Ace Combat 5 Track 91/92: The Journey Home (ending theme)

My pick from GT1 (Mr. 4WD - JP version)
My pick from GT3 (Slipstream)
My three picks from GT4:
Light Velocity Ver. II
Don't Kick Yourself
Moon Over the Castle (Extended Orchestral Version)
-----
My pick of the Pokemon series:
Route 104 theme (R/S/E)
-----
My pick of the Need for Speed series:
Aquila 303/Romolo di Prisco - NFS III: Hot Pursuit
Although I got quickly bored of playing it, I do also really enjoy the menu track for NFS World,
"Static" by Mick Gordon.

Speaking of menu music, some of my favorite tracks in games often come from the main menus.
Test Drive Unlimited's (PS2/PSP versions)
soothing menu track (which I seem to recall isn't an original?).
Battlefield 2: Modern Combat's (PS2)
epic menu track.
Burnout 3's upbeat menu track,
"Ozone" by Stephen Root and Steve Emmy. This is one of my favorites more for nostalgia than anything else.

One soundtrack that is one of my favorites in its entirety is the soundtrack to Ratchet & Clank: Up Your Arsenal. The tracks are diverse and epic. I love all of them, but my favorite of the bunch has to be
the Kavu Island track.
Another is Ace Combat 4: Shattered Skies' 48-track soundtrack, which is an easily identifiable musical predecessor of Ace Combat 5's epic orchestral style. My two favorites from this soundtrack are
Safe Return and
Whiskey Corridor.
The soundtracks to BattleZone (PC) and BattleZone II: Combat Commander (PC) are easy favorites for me. BattleZone because it is among my favorite games of all time and its soundtrack, while not the highest quality, sets a great atmosphere pretty unlike any other soundtrack I've come across. I never played much BZ II, but the first two tracks of its soundtrack (the first four minutes of
this video) captured me when I did.
-----
Single tracks that are also among my favorites:
- Battlefield 2: Modern Combat (PS2) - Heavy Tonnage. I always loved the atmosphere this track made, and it fits the mission it plays during perfectly.
- Driving Emotion Type-S (PS2) - Best Tone. I've never played the game, but I'm heavily into Japanese jazz fusion, which is what this track is. I love it.
- 007: NightFire (PS2) - Atlantis Music.
- GTR2 (PC) - Assassin.
- P.T.O. IV (PS2) - Sea Battle 2. This rip isn't good quality, but it's the only one I can find anywhere. P.T.O. IV is an old naval fleet commanding game nobody knows about. Pretty fun, and it had this awesome battle track in it.
