"Potential for Anything" from
VVVVVV is probably my favorite track from the game. I really like its emphasis on echoed square waves; gives the area a feeling of vastness that most of the other (still very excellent) tracks don't quite evoke.
I'm also a really big sucker for nostalgic-feeling songs - generally warm songs with a hint of melancholy attached to them.
Braid's
"Downstream" and
"Lullaby Set",
Fez's
"Home" and
Minecraft's
"Sweden" and
"Living Mice" all manage to evoke that sort of feeling in me (dunno about anyone else).
Also, this is where I'd pimp "Fortune Night 1"/"2", "Jade Creek 1", "Trap Hideout" and "Battle Glacier 1" from
Freedom Planet, except the game's not out yet and I can't share the music because NDAs. Should come out June 30th, at least, but for the meantime, you'll just have to take my word that the music for it is
really good. I can link
"Relic Maze 1", at least. Admittedly they're more action-y than the songs from the games I listed above, but then those games are more puzzle-y while this one's more of a proper '90's-ish mascot platformer, but hell, they're all good.
Oh, and almost forgot:
Damdadaadam daadamdaa, damdadaadam daadam daadam... Admittedly "Following Stanley" is kind of repetitive after a while, since it's a fairly short segment of the
Ending, but at the same time it's just catchy enough and
so upbeat, it's hard to begrudge it.
