Gonna submit 2 from Dark Souls 3 since I’m playing it for the 15th odd time right now and it’s fresh in my mind:
Iudex Gundyr, the full version, not the shortened version from the OST, and Dragonslayer Armor(Also the best Boss in the series, fuckn’ @ me).
Putting my Manditory Metal Gear Rising vote to A Stranger I Remain, but again not the OST version, which is even more egregeously cut short than Gundyr’s theme is. For some reason the full version used in the game is still labeled as a Beta version wherever you go.
I gotta put down a vote or two for something from the Sonic series, but DAMN that’s a tough call. I recon I’ll go for good old Live and Learn, but also I’ll throw down It Has Come To This from Sonic and the Secret Rings. Just 'cos not enough people know that game has an absolutely KILLER soundtrack.
Also No Way Back ~Out of my Way~, the version of God Eater’s theme used for the major battles. God Eater does that thing where there’s one key track that gets remixed for different situations basically everywhere all through the series and the fact that I’m not sick of No Way Back after playing through all of the first one and about half(maybe?) of the second says a lot. God Eater is The Shit, yo.
I’ll probably be back with more of The Good Shit when it comes to me.
