It's your next to last week co-hosting a radio show. If you're a DJ who wants to share an earworm with the masses, you make the most of the time you have left and play "Hold On" by Wilson Phillips on the air. For good measure, you sing along with it, as I heard some DJs do semi-recently.
And, why not? Lyrical advice about having a more positive life doesn't get much more basic. Maybe it helped someone. Even if it didn't, it's still one of the most well-intentioned earworms.
