MediaMonkey forum

I am at the end of my rope. I broke down crying today after loading MM because another 20-30 hours of careful work has been destroyed. Again.

I recently added 150 music files to my music collection last week. I carefully rated them and genre tagged them.

When I opened MM today, all that work was gone and destroyed. ALL of it. I just sobbed.

This has been happening for months. I put in so much hard work and effort and then mediamonkey destroys my ratings and tags and genres for no reason I can understand. They are just gone like they never existed. I literally own mediamonkey so I can sort my collection by genre and rating. This is devastating to do so much work again and again and have a ~30% or so chance of all that work just being destroyed for no reason.

Is there anything to do? This legitimately is depressing me and starting to effect my mental health. I am so tired of redoing work I should not have to redo with no idea if that work will even save.

Hi,
Only thing I can think of is that MM actually do not save changes to tag (User setting as it saves tags by default) and on next rescan it reloads old tags.

If you are sure that that is not the case please open support ticket, where we can go into more detailed debugging.

This is a good example: Rating was destroyed even though "summary" retains it.

A lot of times when I rate a song "summary" will not update.

The file itself for this song shows no rating, even though i know for a fact I have rated this song at least 4 times in the last 6 months.


I tried to show screenshots but I was prevented.

Summary shows a calculated average Rating for the Album, it doesn't display an actually saved tag.

As Peke suggested, it may be that tags aren't saved to the files themselves. either because you disabled this or because MediaMonkey has no write rights for the files.
Copying a file for which you set Rating and scanning the copy should show the Rating. If it doesn't it means the Rating wasn't written to the file tags.

What File Type(s) are affected and which Build (Help > About) of MediaMonkey are you using?

It seems to overwrite or erase genre tags and ratings without warning. This has happened multiple times, and it's really frustrating when trying to keep a well-organized collection. Has anyone else experienced this issue, or found a way to prevent MediaMonkey from altering metadata like genres and ratings?

Different issue, and you can disable saving of tags (or make your files read-only).

I think there must be some confusion here about what the issue really is.

To prevent the loss of intentional updates to the data, it is suggested to enable saving of changes to embedded tags. This makes sense, and doing so means the info is stored in both the database and the track itself. A rescan or re-install will theoretically reload the same info. For me when I do this I do not ever get any unintentional changes happening.

Now to prevent random changes to tags, it is suggested to disable this same setting. Does the OP mean embedded tags, or tags as shown in the database - I think the latter is meant.

The root question was why are intentional changes to tags are being lost, and why are random unintentional changes occurring.

Is it possible for auto-tag to run in the background, and make these changes??

Auto-Tag do not affect rating!

Still it is still unknown what file format user tag.

Other thing is that sort of external Auto Rate Accurate script is enabled and it changes tags.

This is very strange as MM do not delete things out of sudden especially with tag data.

I have configured MM to save data into file tags (MP3) and I have had no problems with MM losing tag data, I find it very reliable in that regard.

What I have found slightly less reliable is an occasional display of all 5 stars for rating and an occasional lack of synching play count and date from Android, and it is slightly possible that one of those might be contributing to the OP's somewhat general description of the problem.
