Genius hid a Morse code message in song lyrics to prove Google was copying them.
“Over the last two years, we’ve shown Google irrefutable evidence again and again that they are displaying lyrics copied from Genius,” Gross said.
To catch Google, Genius watermarked lyrics with the help of apostrophes, alternating between straight and curly single-quote marks in exactly the same sequence for every song. When turned into dots and dashes, the apostrophes spell the words Red Handed, which is a smart trick.
