So... as I reflect on this thread... I find myself thinking that Annie Lennox belongs in here somewhere. Somehow.
She's cool and ... not so cool, almost at the same time. Certainly, sometimes, from one note to the next.
She's not one of my big faves, but I have tremendous admiration for her.
Let's just kind of drop a coupla Annie Lennox YTs here.
YMMV, of course.
Train in Vain (I know lots of folks ain't crazy about her cover -- but it works pretty well for me):
... and Alanis hasn't been mentioned, has she?
OK,
now she has.
... and Nina Simone
