Does FB prevent certain links shared to feed using FB.ui()?

I'm unable to post a spotify track to my wall. If i use any other URL
(except a spotify track), it works. Using a spotify track however returns
a 500. I'm wondering if FB prevents links which redirect and if so, how
can I share a link to any spotify track to my wall?
STR: Go to http://www.fbrell.com/fb.ui/feed Change the link to
"https://play.spotify.com/track/1fzJyTCKeZuTSLByCsLRHl" or
"http://open.spotify.com/track/1fzJyTCKeZuTSLByCsLRHl" or any other
spotify track.
Oddly, if you visit the track page on spotify, it will redirect to the
album page. Clicking share on a track will successfully share it to my
Facebook wall, so I know that it is possible to share a spotify track on
facebook.
An example spotify track url (sharing any spotify url will return a 500):
https://play.spotify.com/track/1fzJyTCKeZuTSLByCsLRHl
Adding a trailing slash will successfully create the post, but the url is
invalid on spotify.
