I would like to go through my listens and link all the unlinked tracks, but I don’t want to have to click through all of my listens searching for unlinked ones. Luckily we have a Missing Data feature (Settings>Missing Data). However, I have the impression that the missing data tab does not include tracks that were imported through Last.fm, because I can still find a lot of unlinked listens in my library, but my missing data tab is empty.
Is there an easy way to do this, that I’m overlooking?
Was your last.fm import recent? This may be because the ‘unlinked listens’ list doesn’t update that often - pinging @lucifer to confirm.
It that’s not the case, the next step is to grab more details from you, because then it sounds like a ‘unintended feature’ (a bug) 
May this year. So not really.
Hi!
I looked into this, the missing data does seem to be updated for you regularly. However, we only keep top 100/200 items by listen count in that data. And it is refreshed weekly so its possible that the tracks imported through last.fm have a lower listening count won’t appear there until more frequently listened items go away.
Huh, I had no idea!
I’ve opened a pull request to add this to the intro paragraph (I don’t know if we ever really workshopped a lot of that settings text):
Thanks for the explanation.
I don’t think it’s working, It’s been a week and my ‘missing data’ tab is still empty, while my library still contains many unlinked listens.
There’s a ticket on this issue over here:
(I made this a reply to aerozol’s comment by accident, it should just be a regular post on this thread but don’t know how to undo this)
