Summary0019368: Auto-Tag: fails to detect tracks correctly even when accurate Title & Album OR Album metadata exists
DescriptionAuto-Tag can fail in case Title and Artist are missing, but album exists. Expected that Auto-tag from filename is firstly executed eg. the one that is executed during scan to guess missing tags which will result in most cases of correct auto Tag. NOTE: MM5 better detects missing Tags than older MM versions, but users migrating from older MM versions or have "infer properties" disabled.

This is very hard to replicate as for most of Albums it finds correct metadata information and it is hard to find Album where changing/filling single metadata changes the result where Fingerprinting should get the same result no matter of metadata missing.

I have tested on 40+ Albums with various metadata missing and in most cases repeating Auto-Tag (for those that initially you are not satisfied with results) end with correct metadata.

This Sample Album get same results each and every time and can be clearly used to test Auto-Tag accuracy, because correct Album is listed if you click on album name in Auto Tag dialog.
Steps To ReproduceSteps to reproduce:
1. Disable "Infer Properties" in Options -> Library
2. Using folders navigate to sample R.E.M. Album (Supplied on FTP)
3. Initiate Auto-Tag -> Track 5 will be detected incorrectly -> Cancel Auto-Tag
4. Execute Auto tag from Filename to populate Title
5. Initiate Auto-Tag -> all tracks are correctly detected and Auto-Tagged
NOTE: Sample Album is uploaded to FTP under "/Testing/MMTestData/TaggingTests/"
TagsNo tags attached.
Fixed in build

1) There's a progress bar already in the dialog. No need for a second one.
2) I disagree--as long as the status bar shows that lookup is incomplete, it's reasonable for the tag operation to no t be allowed.
3) The cancel button works for me.

Reopen Clean install of 3010 observe same issue when "Infer Properties" are disabled.

NOTE: Point of disabling "Infer Properties" is to simulate empty fields and/or incorrect imported "Infer Properties" and rely on Fingerprinting and existing information.

5) Video file and full MM LOG is uploaded under /MM5/bugs/bug19368/ Sample Album is uploaded to FTP under "/Testing/MMTestData/TaggingTests/"

To explain this issue, it describes cases in which MM 2024 fails to accurately auto-tag a full album that contains partial metadata. The bug is particularly annoying because MM's autotag function appears to ignore accurate metadata that already exists.

Case 1) Can be replicated with the tracks that Peke has shared is which Track and Album fields are filled and accurate. When attempting to auto-tag them, one track consistently is found to be from a different album despite the fact that accurate Title and Album metadata exists and can be matched to the entry in MusicBrainz.

Case 2) Can be replicated with the tracks that Peke has shared by first deleting all Title metadata (so that only Album fields remain accurately filled). When attempting to auto-tag them, two tracks are consistently is found to be from a different album despite the fact that accurate Album metadata exists and can be matched based on timestamp to the entry in MusicBrainz.
