On Tuesday, U.S. District Judge George H. King issued a ruling that should make celebrating your birthday a little bit happier. For the better part of a century, the song “Happy Birthday to You” had been locked up under copyright claim, and those who wanted to officially use the song had to pay royalties to the company that owned its rights. These royalty payments were often collected from stage productions, television shows, movies, and even greeting cards, whenever they decided to use the celebratory song. However, after a long 80 years, King has rendered the copyright invalid, since the original only granted rights to the explicit piano arrangements and not the song itself.
