I need some help with my Samsung Yp-Z5 MP3 player. Does anyone know how to erase my current music on it so I can put on all new playlists? I am new to this technology and it's driving me up the wall There is nothing in the user manual ! I am using Windows Media 10 Player. Otherwise, I am very pleased with it. I will need a blow by blow account...........I am a real dork when it comes to anything like this. Please can anyone help me ?
