How is digital pay-radio different from regular radio?
Regular radio is transmitted through either the AM (amplitude modulation) or FM (frequency modulation) band. AM stations can broadcast their signal a fair distance, especially at night. It's not unusual to pick up AM stations hundreds of kilometres away on a clear night. The problem with the AM band is the quality of the signal is not that good.
FM radio was developed to improve the quality of the signal. You can get rich stereo sound – but the signal can't be broadcast very far.
With satellite – or digital – radio, you get near-CD quality sound. Your car radio can pick up the signal the same way your TV can pick up digital television channels. In addition, a satellite radio channel can carry extra information; while a song is playing you can find out, for instance, when the performer will be on tour in your area.

The Canadian Recording Industry Association (CRIA), an organization that promotes the interests of Canadian record companies and artists, reported today that net music sales in Canada declined by $23 million, or 4 percent, to $608.7 million in 2005.
The CRIA said the decline resumes an almost decade-long spiral paralleling the rise of music file swapping on the Internet and continues unabated due to the failure of the Canadian government to enact much overdue copyright reform.
