How do you transfer music tracks to a PC then transfer them to an MP3 player?

I have a MP3 Player as well. MAke sure that you have the software that the MP3 player came with (usually a CD)...Install that to the computer. When it is done installing, plug the cord into your MP3 player, then make sure that the cord that you just plugged into your MP3 player is connected to the area that it can plug in to on your computer.
