Pretty much anything country, as long as it's 1990's and earlier. Some of the newer stuff but not much. Other than that anything mellow. I can't handle intense music unless I'm really in the mood for it.
I love Christmas songs, but there are only a few that have been recorded in a way that I like. I love to sing them. I'm not big on instrumentals because I love to sing. So when I hear music I want to be able to sing to it.
