AMARTÍNEZ, HOST:
Olympic sprinter Usain Bolt is known as the fastest human being in the world.
(SOUNDBITE OF ARCHIVED RECORDING)
UNIDENTIFIED ANNOUNCER: Streaking away already, it's Bolt all the way. He's looking around again. Watch the clock. It's gold for Bolt - a new world record for Usain Bolt.
MARTÍNEZ: Bolt won eight Olympic gold medals. He retired from sprinting four years ago.
NOEL KING, HOST:
Now he is going for gold again - this time, a gold record.
(SOUNDBITE OF SONG, "IT'S A PARTY")
USAIN BOLT AND NJ: (Singing) It's a, it's a party. This is how we do it seven days of the week. Girls, them getting naughty (ph).
KING: Nice. That's from his first album, a mixture of reggae, afrobeats and dancehall music. There are also some ballads...
(SOUNDBITE OF SONG, "DAYS LIKE THESE")
BOLT AND NJ: (Singing) I'm always having days like these. I just need a break
KING: ...And a little bit of rap.
(SOUNDBITE OF SONG, "IT A WORK")
USAIN BOLT AND CHARLY BLACK: (Rapping) Babe, let me love, let me love, let me love, let me love, let me love, let me love, ya.
MARTÍNEZ: The album is called "Country Yutes." The country, in this case, refers to Trelawny Parish. That's a small town in Jamaica where Bolt grew up.
(SOUNDBITE OF SONG, "LIVING THE DREAM")
BOLT AND NJ: (Singing) 'Cause I came from the country living the dream. Work hard every day. Never change up the routine.
KING: Now this is not the first time we've heard Usain Bolt as a musician. He's released a few singles over the years, and so far, his music career is a lot like his career on the track. Not long after its release, "Country Yutes" sprinted to the top of the reggae charts.
