[chipmonk331]

I have been a fan of them for over 15 years. And I still listen to their music. Even their earlier songs. A lot of their earlier songs are on my ipod along with their newer songs

I'm a guy but admit It would be amazing being one of the them, envy scene. Take a look at 03:02. Could imagine a lot of hot girls crazy for you ? , This song is fantastic for a night in da club.

[pioneer32]

wither u like them or hate them or think there gay like some anti boy band fans think, u cant deny there sucess and there talent, they keep it real and still going strong, I wonder what the teenage girls who are use to now a days music think of BSB now, and wonder if they ever went back and listened to there older stuff, Admit it you would love to be adored by millions of girls world wide

I like their voices. I'm too young for have listenned to them in 1996 but I listenned to their old songs, and they have always been good :) I love that 90's pop!!! I would like to have 17 back then instead of now haha They are part of the pop artists of that time not doing lip sync :D They are real :D
