Third times a charm, right? Apparently I suck at proof checking videos. I didn't realize the audio on this one was weird when I posted it. It should be fixed now. As for my sanity, well...that's another question.
Original music and footage from FF7 remake. Video made using SeeMusic. Audio and MIDI rendered using Musescore.
