Radio changes to Last.fm from Tuesday 15 January 2013
Last.fm is making some important changes to the radio services we offer around the world. We have considered these changes carefully, in response to various factors that affect our business differently in parts of the world.
The key changes are as follows:
In the United States, United Kingdom and Germany, radio in the desktop client is now a subscription feature, as it is elsewhere.
In Canada, Australia, New Zealand, Ireland and Brazil, there will be no significant changes to our service.
Unfortunately, in all other countries, we are no longer offering a radio service after this date.
Hopefully this will change in the future as the system was really good. But thanks to Steven, new alternatives are allready added.
