I belive that the bsb are part of an evil plan to take over the world. They maybe negotiated with extra terrestrials or are extra terrestrials themselves, but they belive if they can use their good looks to hypnotise young, vulnerable, girls, they can get them to listen to their music. Mixed in the words of the music are seceret electrical forces that pull out these girls' brain energy and send it to the bsb's home planet. There, the residents of the planet feed off the knowlege they get from these millions of girls' brains, and soon, if people keep listening to the bsb, the aliens will gain enough intelligence to come to earth and take over, once here, they can force us all to listen to the backstreet boys, and they will soak up everyone's intelligence. Then, instead of just a few teeny boppers having no brains, the whole planet will be a festering pool of mindless zombies.
