I have added Discogs plugin and put in my PIN, then went into preferences tags 2 and made sure it is there and moved its priority to 1 and saved. I then closed MB and restarted then tried auto tag album entered Jerry Reed in album artist and The Bird in album then click find and I get 5 results of which none are right. I do not get any from Discogs but when I go to Discogs site and search it there the information is there but is not from MB album auto-tagger. So it looks like it is not accessing Discogs plugin.
