shaney, you fill the iPod up with music and listen to it whenever you want. You can download CDs you already own, or buy songs - one at a time or whole albums - from iTunes store (or Amazon or other music sites), or you can just download things from YouTube for free. I have basically recreated the 1960s on mine, though there are one or two songs I have been unable to locate anywhere. I have NO rap songs and NO Engelbert Humperdinck, though you may have prejudices of your own to indulge.
You can tag songs different ways and make up playlists - "sad songs", "1965", "brass bands", whatever you like.
You normally listen through headphones but you can plug it into players with speakers, which looks like what you've won. It will probably also recharge the battery.
I think they're wonderful. I don't have a mobile, I don't do FB, I don't tweet, but this is my one device for modern living.
