WITH ITS ABILITY TO randomly pluck and play songs, iTunes’ Shuffle feature has won over a huge number of fans, especially those who don’t want to think about what to listen to as they noodle around the Internet. To start shuffling, click the twisty-arrows icon in the bottom-left corner of the iTunes window.

You’re not stuck with a single shuffling method, either. Some days you may feel like mixing up your music song by song, and other days you may be in the mood to change things up by album.

To control just what iTunes shuffles, choose Controls?Shuffle and select Songs, Albums, or Groupings from the submenu. (“Grouping” is a way to keep certain tracks together in your iTunes library, like separate movements in a piece of classical music that are part of a larger work; Edit Song Information has details.)
