Hmmm...I thought it was my phone...
I ran with Apple Music for a long time, but was disappointed in the long run. I love Google Play Music, and adore the upload music feature. However, I too have noticed the random (and increasing) pauses in music whenever I open/close my phone, or switch to run other apps. I thought it was my phone, but it’s apparently a common issue.
Hopefully this upcoming merge of YouTube Music and Google Play Music will improve the app...so I guess we wait until March?
...but sooner than later on a big fix would be good.
