Wonder why this tune is stuck in my head

I like the Lumineers song "Ho Hey." Though slightly less after the boy got ahold of my phone and managed to:

1. Play the song. 

2. Put it on repeat. 

3. Disable the phone for 15 minutes. 

Needless to say, he loves that song: "Hey Ho," more "Hey Ho." You got it, buddy. 

I know I could have simply turned the phone off, but I was fixing lunch, we were late for nap time and I didn't want to rock the boat. 

At least he hasn't figured out how to make a call "para emergencia."  Yet.
