I have added my music library to tasteprofile (song type) CAPVQY..., every song has item_id as an int64. I have saved those item_ids in local database and hoped, that this will be enough to creating static playlists. Simple playlists works fine
http://developer.echonest.com/api/v4/playlist/static?api_key=UP3xxxx&format=json&type=catalog&seed_catalog=CAPVQY...&artist=Moby&bucket=id:CAPVQY...
But I want also to create playlists based on song. I was so sure, that
CAtalogID:song:item_id
is a correct Rosetta Stone and I thought, that
http://developer.echonest.com/api/v4/playlist/static?api_key=UP3xxxx&format=json&type=catalog&seed_catalog=CAPVQY...&track_id=CAPVQY...:song:4283586156675642324&bucket=id:CAPVQY...
will works, but I'm getting error "track_id - Invalid parameter: "track_id" is not the right type"
Is there any way to ask EchoNest to create playlist based on song identified by item_id in catalog?
