Youtube dreams

Over the weekend I found out how easy it is to use youtube. My younger brother is an aspiring rap and singing artist. He has made his own personalized youtube page. On his page he has uploaded video's of himself singing all kinds of songs. He also has uploaded original songs that he has recorded in the studio. I guess he believes that if Justin Beiber can make it from showing his talent on youtube that he can too. I cannot help but think when I was his age I did not have the opportunity to utilize youtube to post music. I believe that youtube is a great way to have one's music heard. My brother is confident that he will make it in the music industry by posting his music online. I believe it is a hard industry to make it into. I do believe that if he continues to use youtube he will receive feedback. I cannot promise him that everyone will like his music but I will tell him that everyone is a critic so be prepared. He is still young and I do enjoy most of his songs he should use youtube as a promotion tool. I think of youtube in this scenario as a type of public relations to create some kind of buzz. Do you guys think youtube is a great way to create free buzz for a new entertainer or an artist? After Justin Beiber made it who is next why not? That is the question lol?
