It happens out of the blue sometimes.
Could be a new song or an old favorite. For whatever reason it gets lodged in there and you sing those same two damn lines over and over throughout the day until you think you’ll lose your mind.
Just go with it.
Sing it. Sing it loud.
Listen to eight million versions of it until you’ve inoculated yourself against earworm (and annoyed the hell out of everyone around you).
Stop. Listen. Sing:
And if that doesn’t fix you up—go outside and look up.
Look how they shine for you.
