To get music on an MP3/4 player you need a computer/laptop, broadband if you want to download songs from internet using a prog like limewire. Songs downloaded are in MP3 format, an mp3 player will have a usb connection, plug that into laptop and drag and drop files. The iimportant bit is the format has to be mp3 so a bought cd has to be "ripped"(copied) to computer hard drive in mp3 format.
good luck
