In a bit of good timing, Noisetrade.com
just made that Over the Rhine Christmas album available for free. If you haven't been there before, they have a lot of music, most from unknown artists, where you can either leave a tip in exchange for music or give them "noise" (word of mouth) by posting on your Facebook or Twitter that you downloaded their album for free. It's a clever way of spreading word of mouth for up and comers, completely legal, and there's some good music on there.
That felt a bit like an advertisement, but it wouldn't be a Christmas-related thread without some cheesy holiday advertising, now would it?
