They should introduce "Discover Weekly", "Release Radar" and "Enhanced Playlists". Why are the recommendations lacking so much behind Spotify? That's the only reason I can't switch over and I would love to.
I switched from Spotify to Apple Music about a month ago, mostly because I wanted music in Dolby Atmos. (Not all songs are in Dolby Atmos, but many are, and they sound far superior on my AirPods to anything without it.) After transferring my Spotify playlists to Apple, I've found that the experiences are pretty similar. There are a few things I like better about Spotify (e.g., it has better support for non-Apple platforms like Linux and Windows), but I prefer Apple now. If you're curious, I'd recommend a free trial.
