One possibility: This could be a deleted scene or bonus audio from a 2021 indie game or ARG (alternate reality game). ARGs often release in-character audio files with strange timestamps to build mystery. Searching for “boarding house their moans 2 2021011059 min” suggests you already have the file and want to know its origin, or you saw it listed in a directory and are curious. The specificity implies a personal connection — perhaps an old voice memo you recorded, a file from a deceased relative’s computer, or a forgotten class project.
