When I was originally testing with this song, I was sending ENMFP data to song/identify and asking for buckets for MusicBrainz, Discogs and 7digital-US. Now I am no longer getting data for 7digital.
I am using the query http://developer.echonest.com/api/v4/song/identify?api_key=API_KEY&bucket=audio_summary&bucket=song_type&bucket=tracks&bucket=id:musicbrainz&bucket=id:discogs&bucket=id:7digital-US
I was getting 29 tracks, now I am only getting 24 tracks returned. The 5 that are missing are all 7digital-US
Did the fix for studio vs live break the links between this song and the 7digital data?
