Well, I already owned a copy of Fever, but I'm a collector of Kylie. I think this was well worth the cost. The rare tracks, "Good Like That, Baby, Whenever You Feel Like It, and Tightrope," are great, and I have no idea why they weren't included on the album, rather than the two tracks that I hate. And tho I'm NOT complaining, I don't understand why "Butterfly" was included, as its from Light Years. The remixes are also a plus, as its nice to get some variety and a new spin on the widely recognized "CGYOOMH." (And its true, the slipcase actually says "ButterFRY," not "ButterFLY.")
