File System and Naming
The song name that displays is the song name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, then the radio displays the file name without the extension (such as .mp3) as the track name.
Track names longer than 32 characters or 4 pages are shortened. Parts of words on the last page of text and the extension of the file name do not display.
