Really, you can't believe everything you hear in the media. The Spice Girls did not disagree on anything. Mel B recently told MTV Canada, when she was here, that the girls rarely fought, and if they did, it was a 3 second fight. Plus, as solo artists they weren't widely known. Victoria had 1 album out around the world. Emma had a couple with only the first 2 released over here in North America. Melanie C had her first 2 albums released over here and the rest were only released on their side. Same with the other 2 Geri and Mel B. Their first 2 CDs were released over here and the rest were released over there. It's pretty rare to find any of their solo albums over here in stores - though I've managed to find Geri's recent album and the 1st 2 Melanic C albums in Best Buy near my mall. Anyway, The Spice Girls are still girls at heart. They can still have fun, they're not old. Although they're more mature now, and truely are women. The name Spice Girls is just a Label/Name. Labels and Names shouldn't have any effect on what you think of a person or group.
And sure, the people who are buying their CDs are Past fans, just reliving the Spice World, but that's something people enjoy and that's why they're back, for a final goodbye.
