Ok, this whole release is just pure goal, but I'm choosing Sasha's Twilo Mix. His Ultra Violet Mix is just as good and the release also contains mixes from Victor Calderone and William Orbit. If you haven't heard any of these mixes I highly recommend them!
Madonna - Ray Of Light (Sasha's Twilo Mix)
Madonna - Ray Of Light (Sasha Ultra Violet Mix)
And the original for good measure
