ZAK FM
Maybe I’ve missed the explanation, but how have you compared *your* Last.fm radio station to a service like zak.fm?
The difference between zak.fm and last.fm is interface. My personal last.fm stream is only accessible through an relatively complex player inside their cluttered website or through their downloadable software. Conversely, zak.fm is accessible in any browser by simply typing the url and pressing enter. No more control and no more fuss.
