I have noticed several tracks coming back with 2 extra characters added to the end of the Artist field when matching a Discogs release.
It’s always the two characters ", " (a comma followed by a space) that gets added to the end of the Artist field.
These characters aren’t there when viewing the release at Discogs, so could this be a Albunack import error?
One clue could be that all the tracks I have found with this problem have been multiple artist types of the form “x Feat. y” or “x & y” etc.
One example with several of these errors is the Discogs release 835631.
Track 1-1, 1-5 & 1-8 all get the extra characters.
