Spotify comes pretty damn close, if you are in one of the countries they support (UK, Norway, Sweden, Netherlands.) For $10/month, you can listen to unlimited music while online, and offline on your iPhone or PC. For $1/per track, you can download songs to load to other devices. And, using the Facebook integration features, you can subscribe to Playlists (by your friends, or others) that will recommend music to you.
