I’ve never been on the Spotify train, but with an all-Apple household, including HomePod Minis in multiple rooms, I’ve been stuck in iTunes/Apple Music land. We own our music, which is nice. And I dutifully pay the $24.99 per year for iTunes Match so that I can tell Siri what to play on HomePods, but I will be 0% surprised when they deprecate that service.
Anyone have a good non-Apple way of getting Siri to play songs from a personal music collection on HomePods? My kids use it most.
