Player not playing some mp3s

[K9man]

Hello just joined in and must say this is a great site. I bought a nano clone 1gb. have been using it for about a month. All works well but i notice that it will only play about 8 of 10 songs i put into it. I have 9 folders with songs 5 to 12 songs per folder. After playing a song it restarts when starting the next one. I've checked the mp3's 96 to 160 bit rate. My question is why does it play some songs and not others? Is there something wrong with the mp3's (which play on a pc) or is it the firmware?

K9man, Firstly I would recommened a full format in Fat to check the integrity of your memory chip.
Some players have a problem with multiple folders so try removing a few or placing all your music files in one folder and see if they all play.
