Insidious Soundtrack: Where Is It?

I can't be the only person asking this question about the Joseph Bishara composed soundtrack for James Wan's Insidious.

The film had an edgy, ultra creepy, slightly avant-garde score that was beyond impressive. So the big question is: Where is the OST? Why can't I find it anywhere?

For some odd reason, the soundtrack to Insidious hasn't been officially released and is not available to purchase or download anywhere. This is very unfortunate because of how good the original score by Bishara is. Hopefully, with the films increasing popularity, we'll see it with the release of the special edition, we can only hope.
