Copyright Laws

When you go to a restaurant or another place for a usual get together and ask for a song to be sung to you or another for their birthday, you probably will not hear the famous "Happy Birthday to you" song. This is because the song is copyrighted and belongs to Warner Music Group. The group charges $30,000 for anyone who wants to use their song; for example, if it's sung at a chain restaurant,played in a movie, sampled in a song,or downloaded as a ringtone.
