Use Genius Shuffle, Genius Playlists, or Genius Mixes in iTunes on PC
You can use Genius to have iTunes play songs from your library that sound great together. There are three ways you can use Genius:
Genius Shuffle: If you can’t decide what to listen to, use Genius Shuffle—iTunes chooses a song from your library and then plays songs that go well with it.
Note: To use Genius Shuffle, you need enough songs in your library to generate a complementary list of songs.
Genius Playlists: Choose a song, and iTunes creates a playlist of songs that sound great together.
Genius Mixes: Choose a genre, and iTunes plays selections of songs that play continuously, like commercial-free radio stations. You can have up to 12 Genius Mixes.
To create Genius Playlists, Genius Shuffle, and Genius Mixes, iTunes uses anonymous information about your library and other iTunes libraries. The iTunes Store updates its Genius data constantly, based on new information from the iTunes Store and customers’ libraries.
