Can I keep my transfer my iTunes music to an Android phone?

Sorry to hear you're moving away from your iPhone!

To clarify, if you have an Apple Music membership, you can access Apple Music tracks on your Android device if you have Apple Music on Android (available on the Google Play Store).

If you had music tracks that weren't from the iTunes Store or Apple Music catalog but were matched or uploaded, these will also be available in Apple Music on Android. You'll need an active membership of Apple Music to do access these via Apple Music on Android.

No. The Android software is not compatible with iTunes music.

iTunes is only compatible with iOS devices such as your iPhone, or an iPad, or iPod touch.
