1. The queue is a transient song list, and not an actual playlist. When you add a song to the queue, the Nexus Q owner can listen to the track for 24 hours, even after you’ve left. It’s a kick-ass feature that reinforces the hardware as a sharing platform, but no actual files are added to the device (nor could they be, what with the lack of local storage). By the same token, Nexus Q isn’t a gateway to all your friends’ music collections or private playlists — you can only see the songs that have been added to the queue, not everything a visitor has stored in the cloud.
