Perplexed by the Pussycats

I can't for the life of me figure out how many Pussycat Dolls exist. Weren't there anywhere from 6 to even 8 of them at one point? NOW, in their latest video, there's definitely just FIVE. In fact, in other videos, it seemed to me that the number of them varied from shot to shot. Of course, NONE of them matter beyond the lead singer anyway, so it's REALLY like what the fuck's the point of the others? Why are they even there? They're truly just like backup dancers. And let's discuss this lead singer, Nicole Scherzinger. Most reading this will be stunned I even know her name, but she's actually become reasonably well-known to anyone who follows music. She even was supposed to have a solo album out at the end of last year. I recall seeing TWO different videos at like the same time...which, to me, screamed "the first single failed, so Holy Christ, let's try THIS one!" But neither single made any impact, and the album never materialized. What the fuck? And now she's back with her other Pussy mates for a new album...presumably only because her solo leap failed miserably. I mean, I remain stunned their one album did so well to begin with...this group that began...um, as some random burlesque act with Carmen Electra, no? I guess that's just it...I've always been baffled by WHAT THE FUCK exactly they were. All too manufactured for me. Same way I felt about The Spice Girls...like they JUST weren't worthy of being on the radio. OK, well, that's just about enough wasted life time on THIS subject...
