As to be expected, with as huge of a following as she does, Lady Gaga has a few fan remixers. One of the most known (because they also do other artist) is DJ Dark Intensity. This DJ has pretty much remixed all of Gaga's released songs and even a few unreleased, my favorite remix so far is the GREATEST remix. Greatest is a beautiful song on its own with amazing background vocals and DJ Dark Intensity used that as an advantage.
