I've added all the weekly videos I could find above. Unfortunately, videos of two songs can't be embedded (but viewable on the host sites). Most of the official NBC The Voice videos have been set to private and I don't know how long they will keep the remaining Season 4 videos.
I summarized the iTunes chart info on the first post. If you have any sales data to share, please post them below.
