I wasn't a fan of William Orbit's album on this list, but I think his work combines really well with Madonna. Interesting electronica that goes nowhere matches really well with Madonna's pop-sensibility. The album is a bit on the long side but its full of nice motivs and weird left turns to keep you engaged. I loved hearing the snippets of Arabian and other world-music on here. Madonna also sounds great on this album. Frozen is also an all time classic.
