Re: %CONTENT GROUP% mapping error Reply #25 – 2018-07-18 04:08:21 Quote from: Temerald on 2018-07-04 17:52:16If you will kindly follow the link I provided, hydrogenaud.io's Tag Mapping Page you would learn I'm not trying to change the standard; I am trying to bring foobar2000 up to standard. These changes are not persional, or based on a singular opinion; I'm simply pointing out erroneous field mappings in foobar2000 based on hydrogenaud.io's Tag Mapping Page.@Temerald:You are wrong assuming, that the list on wiki you linked is a "standard" of mapping. There is no standard of correct mapping of the tags of different file formats.In fact, every music software does its own mapping. That is: WinMediaPlayer maps in a different way than iTunes does. iTunes maps differently compared to WinAmp. WinAmp maps in a different way than MediaMonkey. And MediaMonkey maps differently than your Android phone...This is a big problem for interoperability of tagged music. It's a mess and it happened, because there is NO standard.The widely used tagging software MP3tag was initially designed for iTunes users, and it mainly uses the iTunes mapping scheme. And your linked mapping scheme on wiki is based on this software. But again, this mapping scheme produces errors when used with other software.The only way to achieve "correct" tagging is:1. decide the software you want to use2. decide the file format to use3. read the documentation of your software's mapping scheme for your file format or check it out by yourself4. put your information in the appropriate tags, so that it will be read correctly by the software you want to useThis means unfortunately: If you want to read your tagged music files with another software, you first need to "translate" your tags.Mediamonkey found a solution for this. They do double and triple tagging for "ambiguos" tag names: for example, an album artist like "Pink Floyd" is written into a flac file using three Vorbis comments simultaneously: "ALBUMARTIST=Pink Floyd", "ALBUM ARTIST=Pink Floyd" and "BAND=Pink Floyd". As a result, the album artist will be read correctly by a broad variety of software. But that's off topic.
