A closer look

When the Guinness Book of World Records gets tired of tracking guys with extremely long fingernails, they occasionally turn their attention to Detroit rappers breaking the sound barrier. In 2013, Eminem released 'Rap God,' a six-minute sonic assault that was a literal, documented athletic achievement. Containing exactly 1,560 words, he raps at a mind-bending average of 4.28 words per second, eventually cramming 97 words into just 15 seconds. It is a stunning feat of breath control that effectively makes every other rapper sound like they are casually reading a grocery list. It’s not just music; it’s a verbal combat sport.
