Genius on the iPod Nano (4th Generation) Does Not Show Up

I'm having trouble with the Genius feature. I downloaded it to my iTunes on the computer, and I synced my iPod. I haven't really noticed it before, but I've never been able to see the Genius playlist maker on my iPod and I must have synced it about 10 times to my computer. I can make a Genius playlist on my computer, however. Any suggestions?
