Until 2016, the song "Happy Birthday to You" was owned by Warner/Chappell Music. They earned over $2 million dollars a year in royalties, and reportedly sued restaurant chains or other businesses that sang the song in public. Thankfully, the copyright was invalidated and the song is now in the public domain.

So I couldn't have a happy birthday inside restaurants until 2016! And I wonder how they survived that supernova. Maybe they were far enough that the explosion never affected them.

Before 2016, my torturer, who I had to call Master Kepler, used to sing happy birthday for rhythm as she lashed me with her kangaroo whip. She really went supernova on me: I was seeing bright lights even in the day! Then she served me catfish and lamb, always catfish and lamb, boiled in cat urine, and let her rats bite my toes.

I'd hate to think that she was breaking copyright laws...
