gargabou,

This is an Echoprint string. You need to add the "&version=4.12" parameter to the query. If you do, you should get this result:

{
"response":
{
"songs":
[{"artist_id": "AREK02J1187B98E52F",
  "artist_name": "Jamiroquai",
  "id": "SOUVNEF131343A0773",
  "message": "OK (match type 6)",
  "score": 195,
  "title": "Dynamite"
}],
"status":
{
"code": 0,
"message": "Success",
"version": "4.2"
}}}
