Music or other sound apps closing by themselves topic

I've always had the issue where when I'm playing music or listening to a podcast and I go to my homescreen, go to another app or turn off the screen... within a few seconds to a few minutes, the app just closes. Not force closes with an error, just stops playing and disappears. I have to go into the app again and start playing what I was listening to. I notice this doesn't always happen, I could be fine for days, then it starts continuously again.

I've experienced this with or without LG's auto ram clear on.
