I know this is wishful thinking, but wouldn't it be awesome if Madonna released a follow up single and video to promote the whole DVD - Live Album release? But of course, I've always wished she released "Rebel Heart" as a single. In fact, I think it would be a great way to promote this new release. I don't expect anything fancy or even expect a new original video. Though, a video cut from the DVD for the song itself would make sense as she's done that in the past. A heavily promoted single release and video excerpt leading up to its release in September would definitely help generate more interest if not sales.
Again, wishful thinking. 'Rebel Heart' the song would make sense to wrap up this whole era, but what other songs or ideas would you like to see happen to help promote this new concert release?
