When somebody shares a Spotify playlist, the attachment is missing from the Graph API.

What is shown in Facebook:

What is returned by the Graph API:

There's absolutely no reference to an attachment, other than the fact the type is 'link' and the application is Spotify.

If you want to test, Spotify's page (http://graph.facebook.com/spotify/feed) usually has a playlist or two embedded (and missing from Graph API). Also if you filter your home feed to just Spotify stories (http://graph.facebook.com/me/home?filter=app_174829003346), you'll get a bunch of useless stories without attachments (assuming your friends shared music recently)

Anyone have any ideas how to access the playlist details, or is it unavailable to third party developers (if so, this is a very a bad user experience, because the story makes no sense without the attachment).

I am able to fetch scrobbles without any trouble using the user_actions.listens. Also, if there is a recent activity story, e.g. "Peter listened to The Shins", I am able to get information about the band. The problem only happens on attachments.
