I'm having the same problem! It's really distracting becuase I use Spotify with Beats when I do work, so it's really noticable. Right this instant is a car commercial or something. I know it's spotify because it only happens when it's open and only stops when I close it. Even when spotify is the only thing open it happens. I use spotify premium on a family plan so this is really disappointing and maddening when you're trying to be productive.
Yes, it is really very annoying and this problem persisted after brought the issue to Spotify attention. They advised me to uninstall and reinstall the App but even that did not able to solve the problem and I was so fed-up with it that I finally unsub my premium and nowno longer using Spotify.
