The single most popular "Unspecified" track on Spotify is "Ninna Ninna - Lullaby" with 330k plays, due to being featured at the end of the Soprano's third to last episode, "The Second Coming."
The scene has Tony visiting his son in the psyche ward after a suicide attempt. The song is about the son of a bandit being better off dead rather than follow in his father's footsteps, though you wouldn't know it if you didn't speak Italian. Language barrier aside, the tones sync up perfectly. That's the magic of folk, what's old is new, and what's new is old.
This song, and most Unspecified tracks, come from Folkways Records, owned by the Smithsonian Institution. Wonderfully, they have all the liner notes online. In the age of mysterious songs, where media is aplenty but metadata is scarce or scrambled, every bit of context is golden.
