How do I use last.fm in Rhythmbox without subscribing?

If I subscribe to last.fm will I be able to listen to last.fm through Rhythmbox using the plugin available in the repositories, or is there an alternative way to do this without subscribing? I would like to be able to listen from within rhythmbox. Can anyone confirm that the plugin does play last.fm created radio stations if you subscribe?

Solution 1:

Works out of the box- just hit last.fm in the side bar, login & authorise RhythmBox and you can listen to last.fm stations. No need to install anything extra from the repo's.

For some people the lastfm plugin works if you first disable the plugin and re-enable the plugin again.

Solution 2:

(I authorized last.fm in rhythmbox like Gary mentioned, but I can't listen to any stations. However all the information like the track history etc shows up. I also disabled and re-enabled but still I can't create or listen to the radio station.)

A solution for my problem:

I updated rhythmbox by following the instructions here and entering these commands:

sudo add-apt-repository ppa:webupd8team/rhythmbox
sudo apt-get update
sudo apt-get upgrade

I then updated the plugins by referring to this discussion and entered the following:

sudo apt-get install gstreamer0.10-ffmpeg gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly

And now I can play my music and last.fm. However I still can't access the radio stations I already had in my last.fm profile so I had to create a new one, which I don't mind at all, but some might find it annoying.

UPDATE: Starting from last week, it has stopped working and I haven't found solution yet. The checking on and off in the edit plugins doesn't work either.
