Boy bands are teenage boys who were brought together, via auditions by a music producer or producers. Typically, they do not write their own songs, choose their own looks & style, coreograph their own dances, & do not form organically. They have a "handler" or team of handlers who decides this all for them, and they are not "discovered" as a pre-formed group of musicians. Most aren't even musicians, but a band of vocalists. Although members, (eg. Justin Timberlake, Harry Styles) may emerge as musicians in their own right. Thus, Wham! was not a boy band. Bubble gum pop, sure, but not a boy band
