premise: Gary LeVox (born Gary Wayne Vernon, Jr., July 10, 1970), is an American singer and songwriter. He is known for being the lead vocalist of the contemporary Country Pop trio Rascal Flatts, and his stage name is taken from the studio-console label for his lead-vocal track.
hypothesis: Gary LeVox sings lead in a band called the contemporary.
reason: I took part of the description of Rascal Flatts and wrote as if it were the name of the band.  When there are a lot of details/categories/modifiers, I think the AI is confused by the many details.
