Any idea what the world’s best known English language is? Before you guess, here’s a hint. It’s "Happy Birthday". And because of a judge’s ruling on Tuesday, it’s no longer protected by copyright. You might have noticed how at some restaurants, they don’t actually sing the tune " Happy Birthday to You", because they don’t want to get sued.(5)Here’s why: two sisters wrote " Happy Birthday" about 120 years ago. They assigned the music rights to a music company. In 1998, that company was bought by Warner-Chappell Music. And since then, Warner-Chappell has made about 2 million bucks a year on fees for the use of the song, though it doesn’t charge people singing it at home.(6)Anyway, a filmmaker that’s making a documentary about the song sued Warner-Chappell to avoid paying a $ 1 .500 fine.(7)A judge ruled that Warner-Chappell owned a limited piano arrangement, not the actual lyrical song itself. That means it’s free from copyright and free for anyone, anywhere to sing it, like a gift that keeps giving.
