Digital Root - Nine Hours, Nine Persons, Nine Doors

"Digital Root - Nine Hours, Nine Persons, Nine Doors" was a high quality rip of "Digital Root" from Nine Hours, Nine Persons, Nine Doors. It was originally uploaded to the GiIvaSunner channel but was never reuploaded.

Joke
At 0:12, the OST is mashed up and pitch-shifted with "Gangnam Style".
