how to use apple music app
I already have "music" where i download the songs i've bought on itunes. I just signed up for Apple Music to save money.
Is my existing "music" app (red square with white notes) the same as the Apple Music App?
Yes. The red square with white note is the Apple Music app.
You can access the Apple Music subscription service content through the Listen Now tab in that app.
