ive just bought an mp man mp3 player, i tried to download songs onto it from cds and then put them on it using windows media player, my player is a 512mb so i can fit loads of songs on so i tried to put bout 90songs on but when it had finished it had only put 21 songs on and it keeps doing this, ive tried others ways to put it on but that doesn't work ever it jus puts them all on and doesn't let u play them, can any one help please
