Music skips with Spotify streaming on HomePod

I have just started using the HomePod and streaming to it from my iPad Pro. The music takes intermittent skips as it is playing. They are very short but noticeable. Is this because I’m streaming Spotify or would it happen even if I was using Apple Music? I haven’t got an Apple Music subscription yet, but if it will avoid this difficulty, then I will move to it and get rid of Spotify. All advice gratefully received.
