That mystery billboard clip posted a few weeks ago can now be heard presumably in it's entirely on Mixcloud. It was played in a set by DJ Sander Kleinenberg in Denver, CO.
The KICKER is the track was apparently
uploaded 3 months ago.
You can listen to the track
here (the song starts at 2:00).
Couldn't find much on Sander Kleinenberg and Madonna aside from a remix he did of "Hollywood" a few years ago.

Could this be the "dance legend" Billboard was talking about, or do you think this DJ perhaps worked with Madonna or another big star?

*EDIT*
Apparently the clip appeared even longer ago, as this facebook post from June 2013 was discovered - - >
