Turning notifications off would probably solve the problem as it only occurs when the display briefly turns on to display the track change notification. But, to be honest, playing music without notifications is a big bummer… I like being able to instantly see what song is next without having to listen for the first 30 seconds or so trying to figure it out.
It is a shame, I didn’t realise DPS was that big of a CPU hog. Is it possible that you are not able to reproduce it perhaps you have a better CPU that is, presumably, able to handle it better? My processor is: 2.7 GHz Intel Core i5
