Can anyone tell me exactly how all of this works, not only on the phone, but in your iTunes library on the desktop as well. When I 'love' a song, I notice the menu then reads 'remove from my music'. But I thought the love button was just for recommendations. The 'plus' adds songs to your music, correct? And those songs stream unless you choose make available offline? (Sub-topic: Apple needs to add a make available offline button to the full screen player). Also, how does it work when I'm browsing and adding music from the desktop application? I don't mind if the music 'streams' from the desktop, but when I sync my phone, I want all of my music stored on the device.
