This is a bit of a vague question but you should start with reading the manual to your pc and mp3 player if you don't know. second it all depends on what kind of mp3 player you have. some mp3 players allow you to "drag and drop" music into particular folders on the device. Others require particular software in order to convert and transfer music, on the other hand Windows media player has a "sync" menu allowing the easy transfer of music. easy really.
