How do I download songs on my MP3 player?
it depends on what type of mp3 player you have. different types like iPod come with software you have to install into your pc before you can transfer music onto the device (even if you already have the mp3 files ready to upload).
if you're mp3 doesn't come with a disc, you're probably safe to transfer music onto the device via windows explorer (if you're running a windows system). all you have to do is connect the device to your computer through whatever chord your have (firewire/USB) and the computer automatically registers the device. then you can open windows explorer and find your music files, copy them, and move them to your mp3 player by opening the player and pasting the mp3 files.
if you're running iTunes and downloading your music from a website like limewire or bearshare, you're going to have to locate those files and place them in a file you can access from the iTunes library. fwhen you do that, all you have to do is add file to your library.
Do you mean upload songs?
If you already have the mp3s, you should be able to transfer them to your mp3 player for free with a USB (or Firewire) cable. Plug one end into the mp3 player and the other into your computer. The computer should detect it and open iTunes, Windows Media Player or the mp3 player-brand program to help you transfer the songs.
You need to tell us what kind of player you have. Most come with a CD that allows you to interface your player and your computer. But first we need to know what kind of player it is.
