Sounds to me like you have the wrong format for the songs to play properly on your MP3 player.
Your player only supports MP3 and WMA type audio files (non-encrypted).
You may have to change the format of your songs to play on your MP3 player.
If you have to change format of the audio files, you can download a FREE format converter at this page:http://formatoz.com/
For information on your MP3 player go to this webpage:http://www.triomp3.com/media-players/mp3-mp4-players/t2810c/
