Hoo boy
Here I'll share some youtube links and give you the chance to see.
I Fight Dragons - The Geeks Will Inherit The Earth
Anamanaguchi - Bollywood
Glaze - Pixel Rush
Unicorn Kid - Animal City
I Fight Dragons is like Alt. Rock and Classic Rock mixed with chiptune. But it's legit chiptune done on nanoloop, MIDINES, and LSDJ so it's pretty cool.
Anamanaguchi is kinda the same as I Fight Dragons, but more chiptune, less guitar. That particular song is off the Scott Pilgrim vs. The World video game soundtrack (they did all tracks for the game).
Glaze actually usually does brony fan music, but Pixel Rush is a really good chiptune sounding song.
Unicorn Kid does rave/dance chiptune, and a bit of dubstep chiptune too, which is actually interesting.
