Super interesting. We could stretch the technical arguments though. The play/stream is broadcast exclusively for me, sure. But then again, see my point below about Spotify being peer to peer application. It is, from an interface perspective, provisioned for me. But really songs are broadcast by individuals to other individuals. In the long run, this line of thinking is fun, but not much else. What matters is what it feels like, not how it's accomplished. And you know what, it's a pretty cool optimization from a technical perspective - gets my respect.
