I was under the impression that the bitrate was not selectable on Spotify Premium but that if you have Spotify Premium on your PC you will get their highest bitrate available. Usually this would be 320kbps.
Also consider MOG if he will only be using it on a PC as it is only $4.99 per month with the higher bitrate as opposed to Spotify Premium at 9.99.
