Seeing as my original source was an fserver in IRC, I'll point you to an alternate source on BT -->HERE (
http://torrentreactor.net/view.php?id=98697)<--. It's a compilation of albums from the series, but it has the second OST, and if you use a BT client that allows you to select a portion of the BT to download, you're all set ^^.
[Edit] It bears noting that at the time of writing this post there was at least 1 seed for the BT. If it goes kaput or something, I'll see if I can find another source for ye~
