Examples of org.jaudiotagger.tag.Tag

org.jaudiotagger.tag.Tag
This interface represents the basic data structure for the default audio library functionality.

Some audio file tagging systems allow to specify multiple values for one type of information. The artist for example. Some songs may be a cooperation of two or more artists. Sometimes a tagging user wants to specify them in the tag without making one long text string.

The addField() method can be used for this but it is possible the underlying implementation does not support that kind of storing multiple values and will just overwrite the existing value

Code Examples:
```
  AudioFile file = AudioFileIO.read(new File("C:\\test.mp3")); Tag tag = file.getTag();  
```
