Pandora stops playing after each song, and sometimes mid-song
I finally solved solved this problem, but all previous posts with this question were closed with no real answer. I'm using the free Pandora in Chrome on a MacBook Pro with Mojave.
I turned off popup blockers for just the Pandora website and it no longer stops playing after every song.
Hope this works for you too :)
