How do i put music on my new ipod nano?

If your using iTunes then just download the song and click and drag it onto your iPod or it should automatically sync if the box that say Automatically sync..., is checked, (click on your iPod and click summary). If your using limewire, 1st download the song, then go to iTunes and click File>Add File to Library then click on the "Shared" folder on your computer under your name. Finally click open and wait a second for it to synchronize to your library. Then repeat the steps that you would as if you had downloaded it from the iTunes store.
