Metal is my favorite, but I enjoy a lot of different kinds of music. I've been on a classical and old European folk music kick lately.
I am a little biased, but my favorite artist is Stills of Drop Dead, Gorgeous/Bleach Blonde/888 (basically the same core people). If it's not already a rule, it should be, if you have a great artist in the family, your favorite has to be them. Inspired (888) is probably my favorite track of theirs these days.
gotta say fav music in general is a mix of classic (pre-1990) country, folk-ish music (Loreena Mckennitt and Gaelic Storm), and Enya, who is so awesome that she should have her own genre.
My favorite songs...too many country songs to list here lol
