Stevie Wonder, Teena Marie, & Wham! are not "true rappers". They still rapped in some songs. Like I mentioned, one of Wham!'s songs is titled Wham! Rap, but is George Michael considered a rapper? Same for other singers who rapped like Blondie (Debbie Harry), Millie Jackson, & Prince. There are rappers who made songs with straight singing like Kurtis Blow, Grandmaster Flash & The Furious 5, Wyclef Jean, Lauryn Hill, Missy Elliott, André 3000, etc. Queen Latifah put out a jazz album and has sung showtunes. Kid from Kid n Play sang the hooks on some of their songs and Salt n Pepa's too. Beastie Boys had punk rock songs on some of their albums. The Beastie Boys also has an album of instrumental funk songs that they played the instruments on. Ice T is the lead singer in a metal band called Body Count. Nelly has released a few country songs with straight singing. The Roots are the house band for The Tonight Show where they play behind artists from many genres and played the music on records by Elvis Costello, Jill Scott, Al Green, Erykah Badu, John Legend, & others. What about rock bands that had rapping and/or hip hop style sounds in their music like Faith No More, Red Hot Chili Peppers, Rage Against The Machine, & Limp Bizkit? The entire Nu Metal genre was hip hop influenced. So is what modern R&B singers like Craig David & Bruno Mars do. Artists were rapping long before it had a name such as Pigmeat Markham, Cab Calloway, Joe Tex, Charlie Daniels, Shirley Ellis, James Brown, etc. So is there really such a thing as a true rapper?
