A new way to find & promote music & videos called Music Nation has hit the scene. It seems geared more towards music specifically where My Space is just a social networking site. Music Nation seems to be more for artist exposure. You can thumbs up or down music, add favorites, become "friends" with the artists, there are tools to add content to your blogs or social networking pages.
Music Nation is just another great find in a vast "Indie" music scene. As you can see I've added one of my favorite songs to the side bar. It took no time at all & now I can listen to this awesome band anytime I log in!
