I cannot get the songs that came with it to come up or delete

While in Windows Media Player (most updated version) there are several drop-down tabs at the top of the window. Select SYNC and a some options should drop down. There should be a command if your MP3 is hooked up that says Actions + (the name of the MP3 player). Click on that and there should be more options click the one that says FORMAT and then OK. This should delete any music that was stored on the MP3
