Updating id3 tag information with itunes speed dating sitediary ru
The Apple Knowledge Base also has posted information on problems with "scrambled" text in tags and how to fix it (article #25293), updating when no text appears in tags (article #88186), and general Unicode text problems—mostly fixed in i Tunes 2.0.2 (article #60954).I recently turned Match on in i Tunes, and it did its thing and matched/uploaded songs.
This is the track data that you can edit manually or via Apple Script.
In addition to the longer text strings, items not supported in ID3 v1.x like i Tunes' Volume Setting and EQ preset are storable in v2.x, but other players and programs may not be able to access that data.
And be aware that Ratings, Play Count, Play Date—items introduced in i Tunes 3—and also Start Time and Stop Time are not stored by i Tunes in ID3 tags (there is a Ratings "frame" in the v2.x spec, but i Tunes doesn't use it because of multiple user complications).
Here is ID3 Tag v1.1: All that, still packed into just 125 bytes, and still the 30 character limit for Title, Artist, and Album.
The next version of the ID3 tag completely re-wrote the spec, allowing for vast flexibility when including track information, however still maintaining compatibility with MP3 players which still used the v1.x tag format.
To cut to the chase, this is the format of ID3 Tag v1.0: So there's 125 bytes of data and that's the order it must appear in.
