Listened, not bought

I've just been reading about the new technology that's supposed to let you download any song that the radio happens to be playing. This is meant to be put into mobile phones and stationary digital radios, and a song would cost 1.25 GBP. The way it's described, it sounds like a client side technology, where the client knows the identity of the song playing on any given station. This would mean your client could continually pick the stations playing your favourite songs at that very moment, without any purchase ever made!

I really hope for their sakes that the inventors implemented this as a server-side technology, otherwise... oh dear!
