Buying all of the boybands stuff is their job.
Also, karen. Boybands have always been popular. It was the solo acts that didn't really get super popular until the late 90s especially female solo acts. As you can see, solo acts sales are declinig while boybands and groups acts sales are increasing steady. The three albums of the year are of boybands and just about every year, a group act/boyband has landed in the top 3 yearly albums.
