If you select the track on the left.
Unless you drag the track down on the right too, you end up tagging the wrong track.
This is not a bug, this is a feature 
Please have a look here:
So that is the purpose of being able to select the track on the lower left panel if you can’t do anything with the selection?
If users end up with the wrong data, then it’s a bug or at least the UX is not ideal / obvious.
If you’re only tagging whole albums, then it makes some sort of sense, but the anigif doesn’t show a single track. There is nothing above the box to the right of tracks to indicate what that box is, or that you need to do anything as a user.
What would you suggest to get the result you want?
Please feel free to submit a feature request if you can think of a better way to suit your workflow.
Just for the record:
The metadata at the top is for the selected track in the bottom left corner. If you click on "A1 Lonesome..." under Tracks, you can see what information would be available for that source track on Discogs.
The lower right section is only for "linking" your left source track (and its metadata) to your existing local track and current Filename.
I guess for me it should be, if I select the meta data in the top left it would be applied, or that the tracks and meta data in the bottom two panels are more obviously linked.
Especially in this case as I was only actually after the genre of the track and ended up getting the wrong title.
So perhaps the box to the right of the Tracks box should say - file changes applied too, that might make it more obvious?
or if there is only one track and you select B2 as an example in the tracks box, the length - filename box should change automatically for single tracks?
How would that work for more files?
Esp. the part where you
Right now it is the other way round: you select the file (and not the data from the list) as the should get the data, not the data should get the file.
As soon as you select the file and move it up or down in the list, you see to what data it gets aligned.
The advantage of that method is that it is applicable to more or less any amount of files without the need to remember several different ways of handling in the same dialogue.
If you select an entry in the track list, then you can check what data is stored in that entry. And that extra information should make it easier to decide if you want to see that data in the file.
After you found the correct item in the list, align the file with it.
So at the moment if you select the track in the right lower box.
The left box is selected as linked
BUT if you select the right box it doesn’t highlight in the same way to show the relationship.
first attachment - select no association - AA selected left.
2nd
A is, but if I then select AA, it doesn’t move down. so if you are selecting the left box first the logic and connection is not obvious to the user.
Or more tool tips ?
What would be the contents of these?
The only list in which you can change anything in respect to order is the right list.
Only the selection in the right list tells you which file gets which data from the left list.
As a user I would be rather upset if selecting an item in the left list as a check of the available data would (up-)set the assignment to the files.
How would you design an easy way to assign the files to data?
The other issue is that the arrow in your first post doesn’t actually line up, it shows between tracks, so when you first release it, it slots into the track above.
The blue arrow should point AT the track it aligns with, not in between tracks.
Try this with one track from an album and you’ll see what I mean.
I may see what you mean but I doubt that this will hinder me from using the function to my satisfaction. And as long as I get the data into the files, I am ok.
Yeah, I think it’s not as intuitive as it could be, but I also see it’s quite hard to make it more so.
I think after doing it twenty times the only thing I can suggest is if there is a track called
title in the album that it tries to match that.
It would also be great to just be able to pull genre back, as that’s what I want 99/100
By default all fields that have been found on the web are selected. If you only select the field for GENRE, you only get that data written to the file.
