This may be old news for some of you but I just discovered a new toy and I can't keep my hands off of it.
Get your minds out of the gutter.
I'm talking about the new Genius feature on iTunes.
You pick a song from your iTunes library, hit the Genius button and, voila, Genius puts together a 25 or 50 song playlist based on that song. And it does a really good job. I've been rockin' out here at MileHighGayGuy headquarters all day.
