Well game music works for me, not necessarily for you. ;c)
You are probably familiar enough with the Super Mario tune (who isn't?) but sometimes games come out with pretty nice sound tracks. An obscure one is 'Morty on the Run'. Less obscure is anything 'Undertale' related (warning, mileage varies since the fanbase is strong but all over the place. This 4 1/2 minute clip is an OK compressed remix sample).
I personally like most non-brooding instrumental music however. It doesn't get in the way of thinking.
