Scratch this paragraph ... they fixed it after finding out the problems.
Here are the differences when logged onto Facebook outside US and behind a US proxy. This is the DMM page when logged on using a non-US IP address.

Here is the same page 2 minutes later when hosted through a US-based proxy server ... note the additional highligted section in yellow that contains the link to the actual mp3 download.

But most obvious is the page status when proxied and when not ... one shows the link whilst the other is blank

Wished DMM would have informed fans earlier instead of the hundreds of posts demanding to know where the links are. (Oh ... and don't bother with the links/addresses shown, they expire after 23 hours)
