I've got about a thousand tracks that are missing the Year tag. My personal preference for this tag is the year the track was recorded, not the year released, but for these tracks, I'll take anything. The tracks have proper Artist and Title tags, but not proper Album tags. I have tried using
Tools > Tagging Tools > Auto-Tag by Track > Identify Track and Update Tags
with "Year" in the Update Fields drop-down and "update blank fields only" checked.
The results are always "failed" with various reasons, such as "no match for artist" or "unable to match name of track." Most of these are not obscure tracks or artists. But when I get a result that says "no match for artist Bob Dylan on musicbrainz.org" I really have to start wondering what's wrong here.
In Tags (2) I have enabled, in this order, Discogs, MusicBrainz, freeDB, Gracenote, and last.fm.
I find it hard to believe none of these sites can match Bob Dylan's "Knockin' on Heaven's Door" and come up with the year. What is MB sending? Is it because I don't have valid Album tagging for these tracks that I'm coming up matchless?
Help and guidance greatly appreciated.
