It's titled "77 Track Megamix". It's actually a piece of art unto itself. Whoever edited this thing did a spectacular job. Not only does the video mix together various scenes from Maddie's videos, but so does the song.
Unlike a normal megamix, which seamlessly flows from one song to the other, this song actually incorporates sounds from almost every Madonna song into it (hence the "77 tracks").
It not only sounds and looks very professional, it's probably one of the best new mixes I've heard and seen in a long time.
