Lady Gaga dance remixes might sound redundant or superfluous. After all, club-ready dance-pop is what the good Lady specializes in, which explains why these remixes don't always feel like they add or change all that much. But unobtrusive isn't necessarily a bad thing. The Sound of Arrows' mellow reworking of "Alejandro," for instance, evens out some of the original's high drama without diminishing it. Elsewhere, it's all in the details: a cute little Latin beat on "Paparazzi," the ping-ponging beats on "Telephone." LLG vs. GLG's take on "Poker Face" is maybe even saucier than the original.
