Okay, so I have this song stuck in my head (not quite as much as that Frozen song).
I've read a little bit about "ear worms", aka - snippets of music that get stuck for hours in your head on an endlessly repeating loop. I've had a problem with this my whole life, and it is almost a relief to know my condition has a name.
Some times I will go to bed with a song stuck, have crazy dreams, then wake up nine hours later with the SAME SONG repeating in my skull.
Lately, it's been this one, which I like. No more Kelly Clarkson, please.
Now I hope to have this video stuck in my head as well.
