Got the Itch?

Got a song stuck in your head???  According to this article from the BBC this is a “cognitive itch.”  And, “The only way to scratch a cognitive itch is to repeat the offending melody in our minds.”  In other words, the only way to get rid of the itch is to scratch it!
Apparently, Mozart couldn’t stand to hear a melody or scale left unfinished and would finish the tune himself just for the resolution!
