Unofficial (Yet still fitting) Dwarf Fortress soundtracks (Some are voiced, but they're written in the in-game Dwarven Language, so, it's more like listening to a foreign folk song).
His best ones, in my opinion:
[sound only:]
[Voiced (Dwarvish), by fictional characters Doren, Minkot & Nil Crowskull:]
("Råsh numol libash thol (Die with your [pickaxe] in the deep)")
("Akur akir akam (Champions are rewarded by Fortune)")
("Nåzom, nåzom Umom-lol (Dream on, dream on, Dark One)")
Why does Dwarf Fortress not have music on its own?

Runescape:
Some years back, they had a game overhaul, and that came with actual orchestral! (Back then, it was about two, three guys with a synth.)
Let me make some comparisons:
