So far, I've managed to identify 42 of the 95 pop icons from the quiz at this site. It's an .xls file, so you need some type of Excel program in order to open it.
Some of them are pretty tough and obscure. The majority are music related, with a slight 80's and British slant to it. One of them is Rick Astley, for cripe's sake, so what does that tell ya?
