Daily prompt: ear worm

What song is stuck in my head at the moment, asks the daily prompt. Well that’s a simple one, ho hey by the lumineers. My son has adopted the song as his song, the effect it has on him is quite amazing. It can take him from a full on red faced screaming upset, to asleep in 2 and half mins. He’s listened to the song that much that I can almost sing the whole song along with it, which he seems to quite enjoy too.
