Hi there!
I'm testing out the Taste Profiles functionality and would like to create some profiles with a fairly large number of songs in each one. The problem is that I don't have Echonest ID's for the songs. So I need to use song_name and (artist_id/artist_name) combinations to identify the songs.
I followed the directions to create a taste profile, but when I try to update it with the list of songs I get an error saying: "Echo Nest API Error 5: Invalid item block in the input: a song_name/artist_name combination can only appear once per update."
I just want to check whether I'm doing something wrong or whether what I'm trying to do is just forbidden.
The docs have a section about creating a profile with a JSON list of songs identified with name/name pairs. But I can't figure out any way to send over JSON in the create step.
Do I just need to send updates one-at-a-rate-limited-time?
