1.)
Cathedrals of Mourning -- Belzebubs
Great animation, even if the music's not... to everyone's liking.
2.)
Mine, Windbag, Mine -- Bastion OST
...So, I generally like soundtracks with a bit of an... industrial feel to them?
Steel Me from the Ragnarok Online OST also fits; there's a reason why these two tracks are in a playlist I've labeled "Steel City". (Also, Mine, Windbag, Mine starts picking up at around 2:13.)
3.)
Yuve Yuve Yu
Er... well. ...Yeah. Also, arrow guitar.
4.)
Captain War -- Top Floor Taivers
I love things that are sea-related, okay? ALSO, ELECTRIC HARP.
5.)
Sirona -- Miracle of Sound
Celtic Metal. 'Nuff said.
6.)
Takao -- Chthonic
So, erm, I like this one for personal reasons. History of Taiwan and all that. Also holy fuck it's in Taiwanese Hokkien.
7.)
Bergentrückung + ASGORE
If you thought Undertale wasn't going to make it on here, you don't don't know me well enough. Favorite track (or, two tracks) in the entire game.
8.)
Dragon Age Origins Main Theme, and
I Am The One
I have a lot of feelings about these two tracks.
9.)
Zegarmistrz Światła Purpurowy -- Tadeusz Woźniak
11-bit Studios used this in
one of the trailers for This War Of Mine, and, well... I have a lot of feelings about THAT game. Damn good game. Highly recommend when you're not depressed.
10.)
The Five-Floor Goodbye
Speaking of good games, Void, I think you'd like this one. It's called Gunpoint. Hell of a soundtrack.
