Ooh, I've heard & seen clips of Owlboy but wasn't really interested in it, but the music is definitely good.

The original Deus Ex's soundtrack. There must be over a hundred different track. Each area has one for normal, combat, conversation, dead... And you can listen to them all through the legend menu anytime. I don't usually like that kind of music, I spend most days just listening to Saxon and Queensryche.

Turrican II on the almighty Amiga.

The first Age of Wonders has some amazing music, and right off the bat too when you launch the game:

Wild 9 - Gulag
One of my favorites... Cant get enough of this game

AND LAST BUT NOT LEAST... Saints Row IV Main Theme!
Glitched out and awesome as all hell <3 <3 <3 <3 <3 <3 <3

Bonus Saints Row: The Third - Main Theme

I didn't see a more recent thread and wanted to post this in honor of the Gabriel Knight sale:

Gabirel Knight 1 Opening Theme(Classic)

Also I wanted to say the new remake opening theme is soulless and lacks the passion of this version. That is all.

Throne of Darkness : https://vocaroo.com/1g70E9A4pJiz

From Sacred 2 Gold: Humans Love Day

Now I'm not a really a big metal fan, but this tune (and I love the MegaDrive game too) gives me goose pimples whenever I hear it. :D

THUNDER FORCE IV Lightning Strikes Again - Metal Squad

Well, I messed that up a bit... o.0

Oh, and the remake of the same tune above, by the same producers, but with much cleaner audio...

STALKER:
Firelake - Dirge for Planet

Monster Train:
Talos, The Architect

Civilization 6:
Christopher Tin - Sogno di Volare ("The Dream of Flight")

Strike Suit Zero:
Strike Suit Zero Main Theme
Strike Suit Zero Main Theme (Subsource Remix)
