No built-in taste in music

Unfortunately, there's no iPod checkbox that will automatically detect which music in your iTunes library belongs to you, and which music belongs to someone else. You can add this function, however, in the following four steps.

Step 1: Blacklisted

First make a standard playlist of all the music in your family's iTunes collection that you never want to hear on your iPod. For mine, I'll call it "Donald's Don't List."

Step 2: Get smart

Now, let's make a second playlist, this time a Smart playlist I'm calling "Donald's iPod," where the Playlist values exclude our "Don't list," as well as podcasts, and any music genres we know we don't like. You can add as many filters as you want by clicking the "+" symbol on the right side of each field.

If your iPod or iPhone can't hold much music, use the "Limit to" function underneath the filter list to generate a finite list of preferred songs that randomize each time you launch iTunes.

Step 3: Check the results

Both your playlists should appear in the column on your left. Check them out to make sure everything is working the way you want. If you find more bad music down the line, just add it to your "Don't List" and it will automatically be taken off your Smart playlist. If you discover a new genre that you want to filter out from your Smart list, just right-click the playlist, select edit, and make the necessary adjustments.

Step 4: Sync it up

Finally, go back into your iPod's device window in iTunes (make sure your iPod is connected). Click on the music tab and set your iPod up to only sync music from the second playlist you created (the Smart playlist). Then, hit the "Apply" button in the lower right corner and celebrate your victory over your family's bad taste in music.
