I would definitely have to go with Reba! I saw her live in concert and she was a blast. I have been a fan of her for close to 10 years now and I have almost all of her albums. Just thinking about it makes me want to find out where her next concert is. I also like Shania Twain when she does more of her slow songs like "You're Still the One" It really is too bad that she and her husband came to such a nasty end, I really believed that there was some sort of magical romance in her live.
