First off, let me premise my post. I hate the term 'boy band". The word band implies that there are musicians in the group. Last I checked, none of the members of NKOTB, Backstreet Boyz, N'Sync, etc. played instruments. So, I will use the term "singing group".
That being said, NKOTB are the most talentless "singing group" of all time. I hate the whole genre, but I know when someone can sing and dance well. Go back and listen to them. The vocals are vile! If I ever have to listen to I'll Be Loving You Forever again, it will cause me to vomit blood. I worked at a Musicland when they were in thier prime and had to listen to Hanging Tough over and over again. Yeah, they are about as tough as my 4 month old daughter. And have about as much soul as my dog.
