The Best Is Yet To Come
Wildfire
Evergreen

Danger is genuinely unpleasant to listen to. This is just assaulting the ears intentionally, so vote goes to Snake by default. BiYtC is a pretty good song, though the franchise has better options.

Wildfire is a good song with a ton of narrative weight if you've played the game. It also builds on several other instrumental tracks that aren't included in this, which is sort of a shame since it's the culmination of a lot of other music. Not something you'd know just from listening to it though. Nothing against Touhou song, just no contest for me personally.

Evergreen is more fun/lively and something I'd let loop while I did other things, but Mortified is pretty nice and this one was very close! No pre-existing attachment to either song, just a slight personal preference.
