Music Nominations Wanted

Thanks to the munificence of a long-suffering sibling and a recent birthday I am looking to buy some MP3 music tracks from Amazon. In the past I've gotten some good suggestions, so let's try it again. I am primarily interested in:

1. Movie musical scores ("soundtracks")
2. Solo piano or piano concertos. 
3. Female vocalists.

In the first category are composers like Jan Kaczmarek, Mario Darianelli, Patrick Doyle, and Gabriel Yared among contemporaries. Of course I love the movie composers of an earlier generation, such as Bernard Herrmann, Victor Young, Maurice Jarre, Ennio Morricone, etc.

In the second category I like much, but not Valium-capsule music, or nambi-pambie nature soundtracks, e.g., waves hitting the shore, seagulls squawking, or whales mooing in the ocean.

In the third category, there are divas like the bluesy EmmyLou Harris, moody Celtic lasses, Puccini heroines, or Broadway musicals.

I do not listen to music dominated by electric bass guitars or any kind of thumpah thumpah ghetto crap. On the other hand Caribbean or Cuban music does interest me sometimes.

Classical music and operas interest me, but not gigantic Beethoven/Mahler type symphonies.

As someone who is impatient at doing internet searches, I will be grateful for any ideas.
