Apple's iTunes 9 includes several new features, and Genius Mixes is one that is grabbing lots of attention. The problem is that many users can't find the option, so it's a good thing that enabling it takes little more than a mouse click or two.
Genius Mixes is a set of 12 auto-generated mixes from the songs in your iTunes library. The tracks in each mix all play well together, and once you start a mix it can run forever, kind of like your own digital DJ that never sleeps.
Update Genius enables the Genius Mixes feature
If you don't see Genius Mixes in iTunes' Library list choose Store > Update Genius. iTunes will gather new Genius information for your Library from the iTunes Store, and automatically add the Genius Mixes option to the Library list for you.
Genius Mixes shows your 12 pre-made mixes
Once iTunes finishes building your mixes, just select Genius Mixes from the Library list and click on the mix you want to play. Rolling your mouse pointer over a mix tells you what type of music it holds, so it's easy to get an idea of what you are about to listen to.
Genius Mixes is a great new addition to iTunes, and will likely come in handy at plenty of parties -- or for writing all night.
