MP3 file with both v1 and v2.2 tag misses metadata #975
Comments
Hello @thoni56 The MP3 file has indeed a headers ID3v2 and ID3v1 header, but also an APEv2 header. Based on their priority, one tag header get precedence over the other and is mapped to These are the priorities:
First one, get priority over the others. They are not combined, only one is picked. Trust me, the metadata may inconsistent in between version, and I will get tons of question about weird combinations if I would combine them. The idea is that a more modern tag header tags precedence over the older one. The tag I have no problem adding mapping from I hope this clarifies things a bit. |
Thank you, @Borewit! Pretty much what I expected. I did not know the priority order, nor that we can actually find which tag/attribute is actually mapped. Nice to know! Unfortunately I have a lot of files ripped with different software, so I can't tell you where this comes from. What I can say is that iTunes finds and sets the TBP attribute, which is why I started investigating why my software did not pick it up. Indicated also here (which probably is a heuristic list and not an official standard). Since the APE tag only contains gain information, I'm guessing that might also come from iTunes (auto-adjust level), but that is just a guess. But then it would seem strange that iTunes would only add this to some files. Anyway, thanks again, I will probably try to remap the tags to a more standard configuration. It is only the files from one album. |
Version 7.11.6 maps the ID3v2.2 |
Thanks! |
I can strongly recommend MusicBrainz Picard for tagging your audio tracks. |
Bug description
When an MP3 file that has tags ID3 v1 and ID3 v2.2 meta data from v2.2 is not transferred to "common".
Running
music-metadata
v7.11.4.Expected behavior
The file has the v2.2 meta data "TBP" which is not transferred to
common.bpm
as expected. The data it is saved innative[ID3v2.2][TBP]
.So even if the double ID3 tags might be confusing,
music-metadata
seems to consider the file having ID3 v2.2 format since that metadata is innative
but there is no ID3 v1 entry.Audio file demonstrating the problem
