If you use Apple’s Home Sharing do NOT upgrade to the latest iOS update (8.4). Home sharing has been removed. Your options now are to pay Apple for Match or pay for the family plan on the new Apple music service. If you have the technical expertise and resources to set up something like a Plex server or move your library to OneDrive or GDrive, you can take those options, as well.
Fortunately for me, most of my music is ripped either lossless or at high nitrates from my extensive CD collection. Even most of mp3’s come from private purchase and not iTunes. Why in the world would I pay for Match? It doesn’t give me anything I don’t already have.
Outside the home, I put what I want on my device at the time. Most streaming is blocked at the office and why should I burn my data at work or in the car? Beside, I’m rural enough that it’s not unusual to not have bandwidth available for effective streaming.
If you’re a kid that has mom and dad paying your bills, this might be good for you. For many of the rest of us? Not so much.
