Well - I gave it a go anyway and signed up with a subscription and here is what I found on Music Videos:
- Music Videos are not available as part of the subscription (you can only buy a download not stream)
- Tried finding some recent Top 40 stuff like "Wrecking Ball" and "Happy". Neither were in the Store
- Downloaded a "High Quality" download but is really not - The video was a 640*480 @ 23.976 encoded at 2Mbps with the 16:9 content in a full matte (see pic) so the quality is even much lower by the time you zoom in.
- DRMed (as expected)
So in summary, nothing has changed, as the record labels are still off with the pixies. There is a far better range, quality, and DRM free material that can be both streamed or downloaded at sites like Vimeo than what I can purchase legally.
They make it hard to throw money at them for some reason.
