"Offline streaming" is kind of a kludge term. To me, if I don't own the songs and they're not immediately accessible to my other software, "syncing" seems slightly inaccurate connotatively. So I went with "offline streaming" because it seems to connote what is going on: localizing my stream, very local.

I haven't had a problem with the Premium service, so I'm not sure which one you're describing as AYCE.
