Chris subscribed to Apple Music and he keeps getting the "beach balling." Leo says that it could be an issue if he's also subscribed to iTunes Match. Turning on Apple Music will take his existing collection and add it to the mix and sometimes it really doesn't work well. This is because of iTunes. iTunes is old, funky, and seriously needs to be rebuilt from scratch. Leo isn't a fan. He prefers Google Music.
Separating streaming out of iTunes has given him a much better experience. And he can upload all of his iTunes music to Google Music. Google understands network services a lot better than Apple does. Other options for streaming include Pandora, Spotify and Amazon.
