It's good to compare both Sirius Satellite Radio and XM Satellite Radio, although both Sirius Satellite Radio
and XM Satellite Radio offer a wide range of channels, including music (100% commercial free), talk-radio, sports and several other specialist channels (ie. music by decade for example). One of the many feathers in the Sirius cap is in aquiring Howard Stern, shock-jock, for its line-up, but there are plenty of other big-names too. Sirius Satellite Radio
also features ABC News and Talk, A&E, BBC World Service, Bloomberg, CNBC, Court TV Plus, C-Span, CNN Headline News, Discovery Channel, E! Entertainment, ESPN, Fox News, Hispanic Talk, Radio Disney, Sirius Trucking Network, The Weather Channel, and lots more.
sports line-up also looks tempting, with the NBA, the NHL, and live play-by-play coverage of each and every NFL game.
