<< The New Kids weren't exactly one-hit-wonders. They had like 5 albums or so. And they defined the modern boyband. They may not be popular now, but that's not because they aren't good anymore, it's because of the way pop is, new stuff comes out alot faster than the other genres, except maybe rap >>
Well, they're a fad, nomatter how many albums they release... to this day you still hear people listening to The Doors, Beatles, Eagles, Bon Jovi, etc, but all these boybandss lose their audience the moment they leave the pubescent age and come to realize how shallow the songs really are. Baby baby may sound good on a song or two, but after song after song after song, you soon realize that's not so special anymore.
