Lady Gaga - Around 26-27 million. (Or could be 20-25,I'm not sure whether 6 million are sales of The Fame Monster separate CD or if they're included in The Fame and The Fame+TFM the combined CD's 15 million )
Beyonce - As a solo artist,around 25 million.
Alicia Keys - Over 30 million I guess.
Christina Aguilera - Over 40 million.
Rihanna - Around 20 million.
Hmmm.... I am not really sure. My R&B favs snatched my Art rock favs wigs so... I remember watching Kate Bush performing And So Is Love in 1993 or 1994 and it said she had sold 5 million records so I think now it would be 6 million. Roxy would be the same or a bit less and Bryan Ferry by himself would have sold less than Roxy and Kate, I know so. Peter on the other hand, sold a lot more than the rest put together, I think I have seen estimates of 20 million.
Worlwide... I don't know. She's country, so, local as hell.
