getting songs from lime wire onto my ipod
 

Im computer illiterate and am not sure how to get songs ive downloaded from limewire onto my ipod, they go straight to my itunes but not sure what to do next, also how do i put my cds onto limewire, i use windows xp

The shared 'limewire tunes' that you see in iTunes is just a playlist...those files aren't actually in the iTunes library. You'll need to find your saved folder & then add to the iTunes library...then you can put the files onto your iPod;)

To to LW's library, click on one of the songs & click Explore. Your saved folder opens. Add to iTunes from that folder. There's heaps more info in the thread below.

As for sharing your music, have a look at this thread for more info.
