I was sort of amazed when Buble exploded onto the scene. Like he came from nowhere as the latest greatest. I totally agree his music is much better than his singing. I remember hearing he was the next Sinatra. That idea quickly faded.
The guy who I think could of been the next Sinatra and I'm a little dissappointed in is Harry Connick who really has some talent. He started out great with his big band, then changed gears to a small New Orleans Funk group and then decided he'd rather be an actor. I've seen him a few times and his first shows were the best. All that said who am I to knock success, just my opinion.
