Query: Great voices

I've loved PCD ever since I heard them on the Shall We Dance soundtrack where they sang Sway. One of them sounds exactly like Christina Aguilera. Although much of what they've done are remakes, they have a good sound. Don't Cha isn't as good as the original but I still like it nevertheless. I like their vocals and their look. I don't know if they have major staying power or are only hot at the moment, but with some of the songs here, they could have a few more top 10 songs to come.
