AMP Radio now features a built-in ID3 tag editor. ID3 tags are a simple, universal way of organizing MP3 files, used in nearly all MP3 software. The AMP Radio playlist reads ID3 tags, and uses them in sorting.
ID3 Tag Editor Window
 
Editing Tags
To bring up the editor window, simply highlight a track in the playlist, and select "Get Info..." from the File menu, or press (Command-I). When the editor window is up, enter all information desired, and click "Ok" to save.The playlist will automatically reflect the changes in the file.
Tag Version
AMP Radio can create tags with ID3 standard version 1.0 or 2.2/2.3. AMP Radio will create a version 2.2/2.3 tag only if needed. If the information enter fits the ID3v1 restrictions, and if the file had no tag previously, AMP Radio will create a version 1.0 tag.
