Mose baer MP3 player
Poor performance

I have purchased a 2GB MP3 Player (MP565-2G, Code - M13CBMC51013637A), I format it with PC and loaded mp3 songs in it, but at the time of playing songs some songs not played well, they play with disturbance and this player also become hang while playing these songs and nothing will work untill the song finished after that it become normal. This problem occurs on many songs and these songs are of good quality as I play them in my PC as well as in my mobile phone and they played well in it.
