Music artist suggestions?

I enjoy listening to Matt Costa, Switchfoot, Jason Reeves, Jack Johnson, The Fray, Taylor Swift, Kate Voegele, Carrie Underwood, Demi Lovato, Colbie Caillat and Kelly Clarkson. As you can see, it's quite a variety but at the same time I'm very picky. No metal, no hard rock, rap, opera, hip hop... I realize that Demi is Disney, but she's the only Disney artist I enjoy, no more bubblegum pop. Also, I prefer songwriters, and lyrics that come from the heart, I don't mind if they're about boys or love, but not like, one night stands, or getting drunk, or anything... preferably a female singer. Also, I don't like when it's too overproduced. Thanks :)
