I'll add another vote for "Songs For Distingue Lovers" and also the Commodore collection for Billie. I recently got "Lady In Satin" on cd (remastered by Columbia Legacy) and I'm not sure if I'd recommend that one yet--my speakers seem to be a bit too revealing of her by then ravaged voice, but I need to listen to it a bit more.
As far as Nina Simone, I have been listening to "Best Of the Colpix Years" alot lately. Sound quality varies wildly from track to track (this is a hodgepodge of singles and live recordingings from the early 60s), but there is a lot of good stuff on it. In particular, it contains a stunning rendition of "House of the Rising Sun" (sadly somewhat marred by iffy sound quality).
