Childish Gambino's Manager Denies Plagiarizing 'This is America' Childish Gambino broke the internet when 'This is America' dropped on May 5. Although fans loved the song's message, some felt that the beat sounded a little derivative. Some listeners alleged that the song was too similar to 'American Pharoah' by Jase Harley. Gambino's manager, Fam Rothstein, denied the accusation. "This song is three years old and we have Pro Tools files to prove it," he wrote in a now-deleted tweet. Harley also spoke out, encouraging fans not to let the plagiarism rumors overshadow the message of both songs.
