Apple should be able to identify your MP3s as long as those songs are also in the Apple Music collection (and you are subscribed to Apple Music). There’s a “Create Station” feature that might be what you’re looking for. Additionally, for discovering new music, Apple Music has plenty of recommendations and curated playlists to check out. Like most machine-curated approximations of my taste, these never quite do it for me and I end up finding new music by exploring artists/producers/labels I’m interested in “by hand”. But in any case, Apple Music is definitely a better choice over Spotify if you want to maintain a collection of personal media files while getting access to a big streaming catalogue and recommendations. If you use iCloud Music Library, your MP3s are cloud-synced to all your devices automatically. Spotify allows adding personal files, but it must be done manually per-device, so it’s quite a headache if you regularly listen to anything that isn’t available to stream (due to business, politics, or simply never having an official release).
