I also commend Boys II Men. I bought their cd "II" a long time ago and I just pulled it out the other day and listened to it. Their harmonies are awesome and they have some good talent. Much better than N SYNC and BSB and that crap.
The Beatles (my all-time faves) were men when they hit. Gotta go with The OSMONDS! Some of 'em were still boys and they were an actual BAND (for better or worse) "One Bad Apple" and "Yo-Yo" still get me boppin'.
My Guilty Pleasure definately
