    Hello I have a website were I publish new music I write. However, I’ve noticed that my .mp3’s fail to upload if I include information such as “involved people”. I receive the error “Unexpected response form server. The file may have uploaded successfully. Check in the Media Library or reload the page”. However, on page reload the media isn’t there, although it does get uploaded to SFTP. There is a bug for it here: https://core.trac.wordpress.org/ticket/63529

    Is it possible to include the ability for WordPress to extend the metadata it can handle in .mp3’s so they can be successfully uploaded?

    The page I need help with: [log in to see the link]

    If I understand correctly, your problem is already described in the ticket you linked to in Core Trac. A fix will apparently be included in WordPress 6.9, which will be released in early December (in a few weeks).

    As far as I can see, all meta data is generally permitted. There are no exclusions here. The problem that the above-mentioned ticket solves is lists that may be contained in the meta data (such as your person lists).

    There is a hook that can be used to control which of the meta data read is used: https://developer.wordpress.org/reference/hooks/wp_read_audio_metadata/

    WordPress fails to upload MP3s with extended ID3 tags (like “involved people”) because its built-in metadata parser can’t read them.
    ✅ Fix: remove extra tags before upload, update the getID3 library, or disable audio metadata parsing with

    add_filter('wp_read_audio_metadata', '__return_false');
