KatetheGreat19 is unbelievably talented (own her CD!), LisaLavie1 and LorenAllred are both amazing singers, and SweetPoffin is incredibly versatile stylistically speaking. AvidActress007 better be on Broadway one day. I love, love, love Nick Pitera (goonieman86)! ijustwanttosing is a very talented vocalist too. I consider Boyce Avenue the best group on YT for sure. For talented kids, I love RhemaMarvanne. This is a very hard question but these were the first ones to pop to my mind. I know there are a more so don't hate me if I didn't mention your fave!
