There are lot of talented singers and musicians out there who don't get chance to show their talent. Mostly because they don't get a platform where they can show their talent and thats the reason they can't make money out of their hobby. There was this one service started last year called {ln:Muziboo.com - Social Network for Music Beginners 'Muziboo} which helps new singers promote their talent.
