Comment (by wonderboymusic):

 [attachment:27574.3.diff 27574.3.diff] makes metadata way more sane for
 audio files. Videos do not need the same treatment. Here is how the fields
 break down:

 * The Title of the attachment is always the title everywhere. When
 creating a playlist, the title is what is shown below each track, that
 syncs back to the server. We use that title in the track list, in the view
 for the currently playing track, everywhere. There is a title pulled out
 of ID3 data on upload, that is used to populate the title originally.
 * The Caption of the attachment is used to override the value shown in the
 track list of a playlist. I have added text on the Edit Media page for
 Audio/Video to explain this.
 * The Description is auto-populated on upload and is the text that is
 shown on the Attachment Page on the front-end for the attachment. I have
 added text on the Edit Media page for Audio/Video to explain this.

 The new "Metadata" meta box shows the values for Artist, Album, Genre,
 Year, and Formatted Length. These values are editable. If your caption is
 empty, the value shown for each item in the playlist is:
 "{attachment.Title}" by {data.artist}. The artist can be toggled on and
 off in the Playlist Settings. The value for the currently playing item is:

 "{attachment.Title}"
 {data.album} if exists
 {data.artist} if exists

 Previously, none of the ID3 data was editable. Prior to 3.6, no attachment
 metadata was generated for audio and video files. This gives the user a
 chance to upgrade their data. New to 3.9, if you visit the Edit Media page
 for an audio or video file that doesn't have metadata, we will attempt to
 generate it for you.
