Going back to my post from a couple days ago, I did what any self-respecting gen-y would do, I googled that shit. Apparently, old people can hear music that’s not actually there, though it doesn’t have to be before they die, and the person doesn’t have to be old.
It’s called Musical Ear Syndrome. Found on Bing: Being elderly, having a hearing loss, withdrawing, and being alone in a quiet environment are all factors that predispose people to hearing phantom music. The name for this condition is Musical Ear Syndrome (MES).
