Stop sync of Now Playing between devices

[davidmeter]

In one of Spotify's recent updates (relatively speaking, compared to the length of time I've used Spotify), they started syncing Now Playing between all devices. So if I'm listening to album X by artist Z in my car and stop the music on song Y, my three other devices will automatically sync Now Playing to song Y by artist Z on album X. I cannot find out a way to stop this. It is extremely frustrating. My driving tunes are not the same as my work tunes. I hate having to pull back up the playlist I was listening to at work after I've gotten in my car and listened to another playlist on my way to lunch. How do I turn this feature off?
