After dark and just before I get off work, but ... does anyone remember I guessed that "glitchhop" was specific to fan music, maybe MLP in particular?

I present three songs performed using pony voices, cut, restrung and stretched/squashed nearly out of recognizability, but sung nevertheless by talking ponies.

I had never heard this style before pony music-videos started gaining steam.
I grant you, the last two are covers, if you will, of existing songs, but I think the description holds true even I can't easily find further examples in my MP3 directory right now.
