#59 MusicBrainz tags should be preserved between conversions

What steps will reproduce the problem?
1. Check "preserve unknown metadata if possible"
2. Use MusicBrainz Picard tagger to tag .m4a files
3. Use XLD to convert .m4a files to .flac files

What is the expected output? What do you see instead?
All of the MusicBrainz tags should be kept. Instead, they are all erased and MusicBrainz Picard no longer automatically identifies the files. This is because all of the tags are erased.

What version of the product are you using? On what operating system?
20111113 on 10.7.2

Please provide any additional information below.

Thanks for the update. I just checked this out and I think it is still broken. I used XLD to convert .m4a files to .flac files. The .m4a files had proper MusicBrainz tags and were recognized by MusicBrainz Picard. However, after I scanned the converted .flac files with MusicBrainz Picard, they were not recognized. They only contained the title, track number, and encoder tags.

Well, what tag?

As long as I've tested, it works. XLD preserves all mandatory tags (MusicBrainz Track Id, MusicBrainz Artist Id, MusicBrainz Album Id, MusicBrainz Album Artist Id) in ALAC files and they are written to converted FLAC files. Of course MusicBrainz Picard recognizes them and treats those FLACs as already matched files.

Maybe it is only for .m4a files? I have attached an example. This file is detected properly by MusicBrainz. However, when you convert it to .flac with XLD, it loses all that information.

It works. I've converted your .m4a file to .flac and Picard correctly recognizes the tags in .flac.

I do not have "automatically add tags if possible" checked. Is that the reason? I thought if I leave this unchecked it keeps the old tags and doesn't add new ones.

Sorry for the confusion. Thanks for the testing!

Of course you have to check the option. If you uncheck it all tags are removed and no tags are written to the output files.

I guess I was confused because the title, track number, and encoder tags were being written to the file. Thanks for the help and fix!

All tags (except the encoder tag) should be lost. You are still confusing something.

Is there any way to get rid of the encoder tag?
