Sis, I take it you are a bit Younger than me...
My generation, we called them "Groups".
"Boy Bands" were White Folks, Knock-Off attempt to produce "R&B" Artists, that appealed to White People.
It is the same thing that they did with Elvis.
Authentic Black Music is "Too Black" for White Folks.
People who grew up on Classic R&B and Soul Music (Pre-Boy-Bands), recognized the Bootleg and whitewashed nature of "Boy Band" music.
If you were a teen or young child, when "Boy Bands" came out, I "Get It".
But if you were raised on folks like Luther, Stevie, Anita Etc... Then you already know what it is.
