Domanda

In Windows 7, .WMA files have a property tag called "Tags" (e.g. song; music; pop;) with the use of semi-colons (i.e. ";") as the delimiter. Do .MP3 files have one? If not, it is such as pity.

Soluzione

MP3 files alone contain no metadata, but you can use ID3 tags within MP3 files to support metadata.

ID3v1 contains these fields:

  • Song Title (30 characters)
  • Artist (30 characters)
  • Album (30 characters)
  • Year (4 characters)
  • Comment (30 characters)
  • Genre (1 byte, giving 256 possible Genre IDs)

ID3v1.1 Added a track number field to this.

ID3v2 adds many more fields, one of which is a user-defined text frame. This can be used for any data you want and could support a "user tags" field.

Why Windows 7 chooses not to use it, I don't know, but it doesn't matter really does it? There isn't anything you can do. What the client chooses to do with ID3 tags is up to it.
