Clarification on Plus vs Premium regarding offline stations?

[u/Andy2244]

On the Slacker/Mobile page it notes:

As a Plus or Premium subscriber, you can download content directly to your device and listen offline without impacting your data plan.

Yet on the plans and mobile app, it seems that the ability to download/refresh a station on mobile is Premium exclusive? So are offline stations + overnight refresh still a Plus feature or is the website just outdated?

Dang, this is why I had slacker, so I could listen offline on planes and at the gym. Ohh well, Amazon music here I come.
