A few days ago Rolling Stone published a story about a song that appeared on the internet some years back and no one can figure out who recorded it, wrote it, or where it came from. It’s not a very good song, but it is kind of catchy, and suitably mysterious. It was apparently recorded off a German radio show in the early 1980s.
It seems like there must be other music out there that is similarly unknown. Why did this one break out?
There is a subreddit (/r/themysterioussong) that is trying to solve the mystery. Someone there posted a list of other mysterious songs, some of which have been solved. Go here.
