Music stutters/"skips" when screen is off [NVIDIA Shield Tablet]

[flyingcow93]

I'm getting pretty fed up with this, its always been in issue and it just wont go away. I pay for premium and this just shouldn't be happening. 

But anyway, 

Whenever the screen is off the music stutters and freezes, it sounds exactly like a skipping cd from the 90s. I found other threads saying turning off wifi optimization fixes it but this isn't an option for the nvidia shield tablet. The songs are also downloaded so this doesn't make any sense to me. This is the only app with this issue. What can I do? If I can't solve this I'm going to have to find something else to play my music from.
