Download iPod Music Legally

You can download iPod music into unit legally or illegally. In US many were sued for the illegal sharing of music. This against-the-law act is caused by the desire to save spending more than the amount we spent on buying our iPod. But why put ourselves on the risk of being sued just because we want to download iPod music at any (free) cost? There is also another way of downloading music without fear. There are different sites that offer free music and some that to be purchased. So, think about it.
