I must admit I have found that music generally sounds better on YouTube.
I guess the major disadvantage is the comments. People behave like a-holes on there. You could upload a song about teaching your pet mouse to ride a bike, and before you know it there will be some fully fledged shouting match between creationists and evolutionists.
Haha, ain't that the truth. But don't disable comments, the more activity the more views. In fact, slip something in that riles either side up, they'll probably make a scornful post in their blogs and on forums, and that means even more Google juice, use them to your advantage
