How do you load an MP3 player?

If your mp3 player came with a disc, put the disc into the disc slot in your computer and follow the installation instructions. If it came with simply a plug, plug it in to the computer (if it's a USB plug, it should be pretty easy to find) and drag your mp3 files to its icon. With a macintosh, it should simply show up in the Finder or desktop, with Windows go to the start menu and click "My Computer" The bar that shows up at the top of the window should be able to open down and display your mp3 player. click that and drag mp3 files to it.
