Where is Nina Simone today?!

[JesA]

Well lately ive been getting into a lot of jazz/soul/blues artists, one of which being Nina Simone. *another in particular being Billie Holiday* Ive read that she's known as The High Priestess of Soul...yet i had never heard of her before hearing Feelin Good on American Idol. if she was so big, why isn't she ever mentioned on specials or countdowns etc? And also, why doesnt she have a star on the hollywood walk of fame? I find it strange that Mary Kate and Ashley Olsen have a star while Nina Simone doesn't. And i also never see any of her music at stores. Ive looked everywhere...Barnes and Noble, Borders, Bestbuy, everywhere. It's like she never existed.
