iTunes 11 for Mac: Play a Genius playlist or Genius Mix
iTunes can create playlists—called Genius playlists—from songs in your library that go great together. You can also have iTunes play a Genius Mix—a selection of related songs from your library that play continually like a commercial-free radio station.
To create Genius playlists and Genius Mixes, iTunes uses anonymous information about your library and other iTunes libraries.
To create Genius playlists and use Genius Mixes, you must turn on Genius, be connected to the Internet, and have an Apple ID. Genius is a free service.
A Genius playlist has this icon 
next to it.
Turn Genius on or off
-
Turn on Genius: Choose Store > Turn On Genius.
-
Turn off Genius: Choose Store > Turn Off Genius.
Turning off Genius turns off Genius Mixes and Genius playlists.

Keep your Genius information up to date
The iTunes Store updates its Genius results constantly, based on new information from the iTunes Store and customers’ libraries.
Your own Genius results are automatically updated once a week when iTunes is open. You can update them manually—for example, when you import music to your iTunes library from a CD or a website.
To update your Genius results manually:
Choose Store > Update Genius.
