Digital Home Thoughts: YouTube Promoting iTunes Songs for Sale

I don't know how long YouTube has been doing this, largely because I don't use YouTube as a music discovery service very often, but I think this is a great idea. From what I can tell, it doesn't look like the video I saw this in was an official Tokio Hotel account - it looks like a fan upload. Instead of YouTube taking out their heavy copyright club, they instead use it as a promotion for people to buy the song. Clever move! Rather than turing the fans into "copyright criminals", YouTube (and the copyright holders) are taking this opportunity to turn this into an opportunity to sell people the song. This is the way it should be done. Bravo YouTube!
