Leave an iTunes Store page open, kill your laptop battery

I had a similar epiphany a few years ago when I left System Preferences open on the Trackpad pane – the demo videos showing gestures were chewing up CPU, and therefore battery life, even when other windows covered them up:

Just when you think you’ve seen it all from iTunes, it finds yet another way to screw you.
It only applies to the iTunes MUSIC store. If you leave it open on the App Store or TV or movies, the CPU usage is very low.
