After entering the code on the Redemption website, please check your junk mail folder to make sure that the email with your soundtrack download link did not get caught in your spam filter. The email would be from email@example.com.
Here are some other things to try if you are not able to redeem the code:
Make sure you are using dashes in between the sets of characters: XXXX-XXXX-XXXX-XXX
Make sure that all of your alphabetical letters are capitalized.
Try a different browser with plug-ins disabled and pop-up blockers off
Copy and paste the link from your email into the browser, rather than clicking in the email
