I never want to turn it on, but I do swap from shuffle to regular (depending on whether I want to listen to just the newest stuff I’ve added), which means I have to click through smart shuffle now too.
Which wouldn’t be a huge problem, but if you do it too fast, smart shuffle appears to be off, but the songs it has added are at least partially still in the queue.
Doesn’t always work, especially if you need to work with any sort of calendar or recurring schedule.
