Fetching wrong ISRC
I have created a report that identifies potential bad links between Acoustid and MusicBrainz ordered by artist credit, this makes it very easy to remove bad links for your favourite artist.

Please take a look, if everyone just did a couple of artists we would quickly improve the quality of the Acoustid database, and this would improve matching used by SongKong and Jaikoz (and other tools that make use of Acoustid)
