Hello,
I'm just discovering since a couple of hours the wonderful world of the musical fingerprints and music tags.
So, I downloaded a music from youtube (http://www.youtube.com/watch?v=Zi_XLOBDo_Y : Mickael Jackson - Billie Jean. The same one as used in the doc's examples) with the well known youtube-dl. Then, I've launched an echoprint-codegen command to give me the fingerprint of this song (it's the only information I have : no ID3 tag at all) :
echoprint-codegen mymp3.mp3 > query.json
And I tried to execute a request to the API in order to get much information as I can about my song (artist, year, album, etc.) and complete its ID3 tags :
curl -F "query=@query.json" http://developer.echonest.com/api/v4/song/identify?api_key=MY_API_KEY
But the API is giving me this response :
{"response": {"status": {"version": "4.2", "code": 0, "message": "Success"}, "songs": []}}
So, everithing is ok, exept that there is no song in the list... WTF ?! Did I do something wrong ? Did I misunderstood the functionment of the API ?
