Multiple copies of songs

Have transferred mp3 music data across network to wd tv live unit. Now when we go to play music appears to be multiple copies of the same track, sometimes 20 copies of the same track.
Any clues as to why and how to fix?
Thanks

Hi,

As a recommendation, you can try going to the settings of the media player and and turn the media library off and reset the media player and turn the library back on.
