I just tried your plugging.
Not many song yet so I tried through a web radio. Well it did work for one song so far, but other are returning nothing.
May be it is because the song i Listen are French only and not mainstream so the DB dont know thoses song or because of the plugging ?
The fact that make me post here is that every time the script perform the search he cropt the last letter of the artist name (at least from what it is displayed to me).
See screenshoots :
Either it is from the radio stream itself or the script or a mix of both, but what do you think about the "last letter cropped" ?
