S5 and Pandora hesitations with screen off topic

I'm coming from the S3 and never had any problems with this, but on the S5 Pandora gives occasional hesitations (real quick skips) whenever I let it play with the screen off. It might happen 2 to 10 times per song, just depending. Sometimes I can go a while without it happening, but can't figure out anything that's different. It does not seem to depend on signal strength at all, as it happens in areas with good coverage. I thought maybe it has to do with the cpu being throttled down when the screen is off, but I'm not sure...but if so, I would think others would be having the same thing happen. Anyone have any ideas?
