All music streaming randomly pauses on Samsung Galaxy S6

[AC Question]

I have 3 music streaming apps on my phone and for the last few months my phone will randomly pause them while they're playing (doesn't usually play 10 min w/o pausing). It happens when it's plugged in aux, when it's charging, when it's not charging, when not on aux, whether on wifi or not. I read about the Comcast app causing this problem but I don't have that app installed. I tried to research forums online but couldn't really find any leads. It's slowly driving me mad. The music apps are: Pandora, Songza, & RockMyRun.
