Which streaming service has more music?

[Rolando]

No Apple Music, or is this % that matched to AppleMusic?

IIRC, Youtube Music (Formerly Google Music) has the largest library, followed by Spotify and AppleMusic.

AppleMusic offers Lossless and Atmos where available, if that matters to you.

If you have a lot of time invested in Playlists, Spotify will sync them, last time I checked, Youtube Music will not.
