So, last week we showed you a pretty incredible trailer for the fifth (and quite possibly final) season of Supernatural.

While the footage itself was pretty awesome, the soundtrack that accompanied it was quite decent too. Lots of you wrote in to ask where you can find the song and after a bit of digging, we've found the answer.

The song is actually based on an old country track called 'Oh, Death' and was specially reworked for Supernatural's promo purposes by a young lady called Jen Titus.

Best of all, The CW has made it available to download FOR FREE for a limited period. Click here to visit the show's official website then scroll down to the bottom of the page and click the orange 'Download' button.

Supernatural season five begins September 10 on The CW and soon after on Living in the UK.

Are you taken with the show's new soundtrack? Looking forward to season five? Add your comments to this entry below!
