<p>A further reason why songs might not be appearing on your iPod is that the music player application you're using does not support converting the songs from one audio format to another. If you copy a song which is saved in an audio format that is not supported by your iPod (for example, an Ogg Vorbis (.oga) file), the music player will try to convert it to a format that the iPod does understand, such as MP3. If the appropriate conversion software (also called a codec or encoder) is not installed, the music player will not be able to do the conversion and so will not copy the song.</p>
