r@dio.mp3 broadcasts digital music via satellite without any fees or many restrictions. one simply needs a computer with tv-card installed and a cable tv connection. surprisingly, internet access is not even necessary.

although the @ in the name misgives a lot, the technical concept behind the idea seems to be quite smart: radio.mp3 utilizes a gap in tv transmission, the so-called "tv vertical blanking interval", to send encoded mp3 data to the connected machines. since radio.mp3 owns a broadcasting license, they do not seem to interfere with current copyright law. it will be interesting to watch what the anti-napster faction is going to do about that.
