It was a simple toggle button on your playlist and you could clearly see the songs that were added. It was intuitive and useful, so of course Spotify had to go and ruin it.

Now, with smart shuffle, the user has to figure out where are these added songs. Turns out they have to open the que page to see them and they must shuffle the songs. It's so obviously bad and clunky. 

It's like Spotify has one guy who decides what he wants without actually running it past some testers to get sensible feedback. Any rational, long-time Spotify user would prefer the Enhance button feature over this new smart shuffle. 

I've had Premium for many years but this kind of nonsense is making me consider cancelling. Enhance was such a game-changing feature.
