My Last.FM stations stopped working last week - I assume it is due to their protocol upgrade:
We're writing you to let you know that there will soon be a change to Last.fm radio that may affect you. Our stats show that you've listened to radio through an application that uses our old streaming protocol. On 1 December we will deprecate this old protocol, so in some applications radio will no longer work.
I updated to the latest version of Rhythmbox (2.98) with the webupd8team PPA, but still no luck.
Does anybody have this working? If so, what did you do?
