They had one when the show first came out that had about 10 or so songs from the first season and, after the show ended, there was a CD that had every track on the series, but it was only released to the cast and crew.
As for the first CD, they've got it listed on Amazon.com, but it's an insane price (new), though it's not too bad used.
