Android 9 and 9 Plus Music pauses while listening

Android Issue - Music pauses while listening.

I have had an issue with the Android 9 pausing frequently while listening to music. I started to check options and found the issue.

Check your BATTERY POWER SAVING options under SETTINGS>Device>Battery. Take the settings off of Medium or Maximum and change to OPTIMIZED.

Check your Applications (especially music Applications) and verify you have not placed them in sleep mode while not being used. DEVICE CARE>BATTERY. Select Application, Scroll to Bottom and Turn "Put App to Sleep" to OFF. 

This should fix your problem. It fixed mine.
