How to prevent Spotify from running on phone when in use on PC

I think used to be called Spotify connect.  How to disable this useless and unnecessary feature that causes Spotify to run on our phone when using Spotify on a PC?

Obviously I've already read countless forms and Googled everywhere for an answer.  Being told to put my phone in "offline mode" is not a solution.  Obviously I could also turn off my wifi to accomplish the same.

This is an issue because its messing with other apps and draining resources.

If you have a newer Samsung S(#), then you can pull the notification tab down 2 times.  You should see a button that says "Media Output".  Click it, then click the arrow at the top right of the screen.  Next, deselect Spotify as one of the options to play.  That should stop it from playing on your phone while listening on PC.  Hope this helps!
(I just figured it out while reading this thread.)
