It would have been nice if they got Apple Music running properly for all users on iTunes first before adding more users. Like many others, I get slow to load tracks and endless buffering at certain times. It is not me, as I can stream HD video with no problems from other providers. It is so bad I am thinking of going back to Qobuz. I have not had any constructive help from Apple yet, although they say they are aware of the problem, which seems particularly prevalent in the UK, so they are blaming ISP's - "s'not our fault".
