Internet sensation MattyB got his start in 2010 at the age of seven. Born Matthew David Morris, the Duluth, Georgia native is also known by fans as MattyBRaps and has over three million subscribers to his online streaming channel. He discovered hip-hop when he was five, learning to rap and dance with the support of his family and siblings. He first caught the attention of the Internet world with a cover of Sean Kingston and Justin Bieber's "Eenie Meenie," which led to almost a hundred subsequent cover songs -- from artists like Outkast and Bruno Mars -- posted to his channel. Collaborating with his cousin MarsRaps, he began releasing original music in 2015. His debut EP, Outside the Lines, contained four new tracks like "New Kids" and "The King." A year later, he released a memoir titled That's a Rap. By late 2016, his sound had matured on singles like "Can't Get You Off My Mind" and "California Dreamin." ~ Neil Z. Yeung
