Track profile from MusicBrainz track ID

Thanks for the tip Eli, but this still doesn't seem to work very well:

For example, Queen's Bohemian Rhapsody recording id (which is the example on musicbrainz's own site), returns back success, but no actual data:

http://developer.echonest.com/api/v4/song/profile?api_key=XXX&id=musicbrainz:song:ebf79ba5-085e-48d2-9eb8-2d992fbf0f6d

More importantly, for my purposes -- Last.fm's mbid for track.getInfo causes an error: The Identifier specified does not exist

e.g.

http://developer.echonest.com/api/v4/song/profile?api_key=XXX&id=musicbrainz:song:61bf0388-b8a9-48f4-81d1-7eb02706dfb0

Any fix for this?

Thanks!
