MOST PEOPLE’S ENTIRE MUSIC library is too big to stuff onto the wee 2-gigabyte Shuffle, or even the 8-gigabyte Touch or Nano. (Classic owners can chuckle here.) If you love all your music and don’t want to spend time cherry-picking tracks to load up your iPod, Autofill it to the brim with a full serving of tunes.

If you’re a Shuffle owner connecting your iPod to your PC for the first time, the iPod Setup Assistant appears. Leave the “Automatically choose songs…” checkbox turned on, click Done, and presto: iTunes grabs a random collection of songs from your library and copies them onto your tiny ‘Pod. After that, each time you connect your Shuffle, a small panel appears at the bottom of iTunes, inviting you to fill up your player with a click of the Autofill button.
