I currently pay for Spotify. I am considering checking out Apple Music. A couple of questions that I just can't seem to find the answer for after looking at the Apple Site: 1. What is the OFFLINE device limit for Synch for music that is not in my iTunes library (music that I don't own)? 2. I assume the device limit is a combination of computers, ipad, and iphone -- or does the type of device make a difference? 3. Can one sync music for offline at a lower bit rate to conserve storage device like one can on Spotify? Thanks!
