I honestly didn't know this existed till it popped into my YouTube recommended. An unused song for "Faker Lord X" which I assume is just a disguised lord X. It was made by Uptaunt but never released (last I saw it was some drama). Apparently it's from an unreleased (and most likely canned) exe mod called EXE Rival (dunno what that is) so that's pretty neat.
