I can't fathom why they sent me this; the email says i bought some jazz from them sometime in the past. I haven't bought any jazz... At any rate, I'm not sure if any of this stuff is any good. There's a Miles Davis track on one of them, and another has a couple of John Coletrane songs. If you follow the link, look on the upper right of the page. I've downloaded them, but I can't comment on anything because I haven't listened to them yet.
