The beauty of the Internet is that, as long as you have access to an Internet connection, you can send your message to the world, show your talents to the public, and even get paid for doing it and become well-known. The Internet, to a great extent, has taken much of the elitism out of so-called commercial ventures in Entertainment and writing. It's more based on your talent and whether you touch on something that the public enjoys or relates to.
YouTube, of course, is no exception. People, who happen to have a web cam or other video camera, have been able to freely display their talents to the world, not hindered by the need to have "connections" or to impress a panel of judges. The world is the judge. And your talent is the deciding factor. Comedy, music, tutorials and various product reviews and marketing ventures are allowable on YouTube and many people make a living on their YouTube videos and the hard work they put into producing them. All of this without needing much capital, if any: Possibly the most democratic market in the world, this Internet thing.
So, I thought I'd present what I've seen as some of the best cover songs on YouTube, from some of the best artists I've come across on the site.
