Currently indomitable at the top of my list of favourite songs.

Slightly chaotic glitchcore by Lauren Bousfield, who to this day pumps out a lot of cool songs with odd titles. Catchy if you're into this stuff.

Cute little instrumental dance tune. Title is from Homestuck context.

Neo-absurdist heavy metal? The lyrics follow along pretty closely to what you'd expect from the title.

...Some kind of bouncy electronic track with a bunch of different vibe changes.

Half-minute worth of Undertale OST.

Everyone knows this one but I still can't figure out what it's named for. Still one of the catchiest energetic OSTs I know.
