Well, I sorta started this free-for-all and must chime in here, not so much on the Snore-ah issue (I've said what I wanted to say) but on the OTHER question: "Do women singers sing anything but love songs?".
Hell-O? Can you say the one-of-a-kind Nina Simone?
And NOT ONE mention yet of the too-good-to-mention-in-the-same-thread-as-Snore-ah-but-forgive-me-I-just did: Lucinda Williams? Who also happens to be a great songwriter, who can put so much emotion into a song, whether it's love, eroticism, anguish, anger, or (sometimes) lightheartedness it puts you inside her head and inside her heart? I really don't care whether anyone agrees with what I think but if no one has mentioned Lucinda yet I really think you need to at least give her a listen.
Others I like, some of whom are criminally underrated: Linda R., EmmyLou, Nanci G (sometimes), Jennifer W., Alison K., Anita O'Day, K.D. Lang, Paula Cole, Margot Timmins...
Diana K. can sometimes be fun to listen to, not in small part due to great production quality, which actually makes for good audition tracks, as does Jacintha.
