Hi. I have some questions about the taste profile.
The api reference at http://developer.echonest.com/docs/v4/tasteprofile.html#update says that track IDs can be rosetta ID or ENID. Is this a rosetta ID? spotify:track:2EB1aFLWC4uIfld5Z3Yj1z
I noticed that when I create a playlist, there is a one to many relationship between song and track. The results list a song, and associated with the song are many tracks (for example, recordings on different albums).
Is it more effective to update taste profiles using song_id rather than track_id, so as to have the information apply to all instances of the song (i.e., same song, different tracks in different albums) rather than just a single track (a single track in a single album), or is echo nest smart enough to take care of that on its own?
Thanks in advance.
