But it’s still an island. It’s still a self-contained unit. You
have to manage it yourself. It won’t grow unless you manually add
tracks to it. There’s no serendipitous discovery. No social
component. No Pandora or Last.fm-style suggestions that drop
tracks you’ve never heard before, but already love. Google isn’t
offering you a vast, new catalog. It’s just offering to hold your
shit for you.
