Profile read with Spotify ids

Hi,

I'm creating an taste profile and updates it with track_id = spotify-WW:track:1XSNeHpiFie7bv5vL2E2ee (for example).

When I later wants to make a taste profile read to get the audio summary things get messy.

For some songs I get the audio summary for a different track, like in this case San Cisco - Beach and not Boy and Bear Beach.

                "artist_id" = ARYUOHX131529ED7A2;
                "artist_name" = "San Cisco";
                "audio_summary" =                     {
                    acousticness = "0.639028";
                    "analysis_url" = "http://echonest-analysis.s3.amazonaws.com/TR/Wr5HbQVTse-oWPq3hRc5PQQYokzgVmcunid7LsUMETL8rHtygaZXPuZwAYLYc8rnsYiw_5o1yBEX4sYHs%3D/3/full.json?AWSAccessKeyId=AKIAJRDFEY23UEVW42BQ&Expires=1403526879&Signature=UYKGdcVKI2tvQUX3Uig6YXCYIzc%3D";

                    "time_signature" = 4;
                    valence = "0.264683";
                };
                "date_added" = "2014-06-04T13:20:18";
                favorite = 1;
                "foreign_id" = "CAHMGGP1464CAF6B18:song:spotify-WW:track:1XSNeHpiFie7bv5vL2E2ee";
                id = SOGUVHV13B1F7871ED;
                "last_modified" = "2014-06-04T13:20:18";
                request =                     {
                    "item_id" = "spotify-WW:track:1XSNeHpiFie7bv5vL2E2ee";
                    "song_name" = Beach;
                };
                "song_id" = SOGUVHV13B1F7871ED;
                "song_name" = Beach;
}

Whats seems to be wrong? Is it a bug?
