Christine Anne McVie
I know she lived a long, full life, but this one still makes me incredibly sad. She was my favorite member of Fleetwood Mac. Not just a hell of a songwriter, singer and performer, but also she just seemed to have a kind, quiet, and lovely soul. The story of how she wrote "Songbird" is surreal. I'd argue that's one of the prettiest songs ever written, period. Never fails to make me bawl.
