It's excellent. I also have her Light Years, Fever, and Greatest Hits: 87–97 albums.
I started with Fever at the height of its popularity after some friends recommended it to me years ago, then slowly picked up the other ones. Body Language has the same level of polish as Fever, but a broader and deeper musical and emotional range (for Kylie, anyway). I find it less claustrophic-sounding as well. Fever is still a favorite of mine for its intensity and catchiness, but I've over-listened to it and I find I have to be in the right mood to immerse myself in Kylie's virtual disco club, whereas Body Language is more generally enjoyable.
