Regarding the future of this component
The component is still using the old Last.fm Radio API, which was due to be discontinued over half a year ago, and is therefore running on borrowed time. When the new radio API was released I went some way to updating, but hit some problems and then didn't have the time.
However the new radio API requires users to be subscribers in order to listen, and as I expect the continuing popularity of foo_lastfm_radio stems from the fact that you don't need to subscribe, it is unlikely that I'll update to the new API any time soon. This means that if and when the old radio API is deactivated, it will be RIP foo_lastfm_radio.
