Scrape music information

Hi,

I have been using Kodi only for videos. Today added music source for about 100 mp3 songs. Those songs only has artist name and song title in IDtag. I want to use Kodi to download Album/Coverart information just like Movies. However that does not work, nothing has been downloaded after updating the library. The scraper is UAS, also tried other two (comes with Kodi).

Any advice? thanks
