I'm having the same issue some times it's after 1 song, some times after 2 or three. Happens with either streaming or downloaded. Power savings mode is not turned on. I've read issues with Battery Savers - I removed the Avast one that I was using. Still happening. This is always through bluetooth which is the only way I listen to music. My phone can be plugged into charger or not and it still happens.
I'm pretty certain, as I've already checked, that background data for Google Play Music is allowed.
Here's what's weird about it... when I first upgraded to Marshmallow I had a problem with Google Play saying certain songs could not be played because I wasn't online or something. So I reverted back to an older version of Play and shut off automatic updates. Everything was working fine for a couple weeks, then this just started happening 4 days ago. I then updated Google Play Music... still happening. The old issue of songs not available (due to network something or other) doesn't appear to be happening any more.
Any help or suggestions greatly appreciated. Frustrating.
