Snippet: Enable iTunes “Now Playing” Info in Dock ☍

I’m almost embarrassed that I didn’t know about this until now, especially since I always turn off the 3D Dock on all of my Macs (via 512 Pixels):

Using a defaults write command, the iTunes Dock icon can be set to display a “Now Playing” song and artist pop-up that transitions in and out and music starts. It’s a nice addition, particularly if you’re playing songs from a shared network playlist and have iTunes hidden in the background.
