If you add new music to your iTunes library, you may see it download automatically to your iOS devices.
Apple has (finally) increased the limit for tracks in iTunes Match and iCloud Music Library.
I got my renewal reminder for iTunes Match; it doesn’t mention Apple Music at all.
Apple has promised a higher tracks limit for iTunes Match and iCloud Music Library, and an Apple Music app for Android. But neither of them are anywhere to be seen, yet.
It’s confusing, but read this and you should understand.
