Ori And The Blind Forest is definitely up there

Super Mario Galaxy has an amazing soundtrack!

Team Fortress 2 OST

Warhammer 40,000 Mechanicus Just embodies the Techpreist vibe so well, a near perfect hybrid of church organs and industrial music.

Its actually hard to pick a favorite track, it evenly split between Children of the Omnissiah and Noosphere.

Turrican 2 on the Amiga

I can’t pick just one, but these are among my favourites:

• Prince of Persia 3D
• Grim Fandango
• Descent
• Skyrim
• Far Cry 2

MW2: Mercenaries was pretty awesome.

Other ones that come to mind are Crazy Taxi and Tony Hawk's Pro Skater.

I love soundtracks from Splatoon, all series. Especially Chip Damage/Blitz it! is my favourite.

The song from the first level of Sonic Adventure 2 (the one about escaping the city). It catchy to listen to while all of the action of Sonic unfolds.

It's nice to see so many different awnsers, gaming has just so many good soundtracks.

Personally, I love the soundtrack of the original Xenoblade Chronicles. "Engage the Enemy" really hits during the cutscene it plays.

Another recomendation is Xenoblade Chronicles 3's "Words that never reached you"

• GTA Vice City
• NFS Underground 1 and 2
• NFS Most Wanted
• Gris
• Retrowave

For ambience, Anarchy Online.

Final fantasy 6 Chrono trigger Street fighter 2 Street fighter v Super Mario Bros 3 Mega Man 2 Undertale And this is really unfair but Def Jam fight for New York

Total Annihilation

Interstate 76

Beyond Good and Evil

Def hollow knight, I think it captures the essence of a long decaying kingdom perfectly.

Mortal kombaaaaaaat

Pa pa pa tum tum tum pa pa pa

Jet Set Radio Future and Jet Grind Radio. No question. Hideki Nakanuma is a genius.

Oh and Dance Dance Revolution 3rd, 4th, and 5th miss.

That's a tough one. And I don't think it's fair. From one generation to the next, music in video games has evolved quite a bit.

And each console had its own quirks for the music chip. Some later consoles played directly from CDs.

On the NES, I think Megaman 2 and Journey to Silius had kick-ass chip tune soundtracks.

On the SNES, I'd say Uniracer had a great rock soundtrack. Star Fox also had an epic soundtrack. Oh and Killer Instinct was fantastic. It even came with a music CD with the soundtrack. But my all time fave has to be the TMNT IV game soundtrack. And I'll give a special shoutout to Chrono Trigger.

On the Sega Genesis, I think the Sonic series had an amazing newjack and fusion jazz style soundtrack.

On N64, and PlayStation I particularly LOVED the Wipeout racing game soundtracks with music from my all time favorite electronica bands of the time. Goldeneye 007 holds a special place in my heart as well.

After that it gets really hard because so many games have incredible music. It's hard to choose.

TF2

Others have mentioned kingdom hearts, donkey Kong country and Jet Set Radio Future which are some of my favorites, but another one I love is Maplestory. Great simplistic map BGMs that I still listen to quite often when studying or focusing

I still listen to the NSFU2 soundtrack today when I feel the need for a bit of hard hitting sound, with some variety.

Celeste and Pokemon mystery dungeon explorers of sky

IDK if it's best of all time but the soundtrack to Guardians Crusade, a jrpg for kids on the PS1, is pretty up there and waaaaaaayyyyyy better than it has any right to be.

half life franchise (seriously every game has perfect and fitting soundtrack) super meat boy (both the original 2010 soundtrack composed by danny b and the 2015 soundtrack made by various artists rock. but the 2010 soundtrack is one of the most iconic soundtracks ever made in my opinion.)

Risk of Rain 2

Some great ones:

Gyruss (arcade)

Bubble Bobble (arcade)

WipeOut 2097(XL) (psx - probably the best example of songs that compliment the gameplay)

Afterburner II (arcade - just one specific track called City 202, at time 15:34)

Edit: 2 more

720 ( arcade - blistering)

Rolling Thunder ( arcade - max funky )

Teenage mutant Ninja turtles iv: turtles in time

SNES Wild Guns final theme Song

Definitely the best video game music is from Metal Gear Rising: Revengeance. Stains of Time is my favorite.

Ahhh but which Still Alive?

You probably meant the one from Portal, but I much prefer the one from Mirror's Edge! Beautiful song!
