Having had both, I don’t find many advantages of Spotify over Apple Music unless you’re wanting to connect to less mainstream devices/speakers to stream. Spotify is the grandfather of the bunch and this connects with a variety of platforms/speakers/devices. That said, I have had zero issues not front using Apple Music. I only switched because it was included in Apple One and I saw no reason to pay for two services, but with Spotify continuing to raise prices so frequently, I’m not inclined to ever go back unless they can provide a value proposition for those price hikes.
