I subscribe to Dish, and part of what they offer is Sirius digital music channels. About 100 channels, no commercials (except for Sirius' own), and each channel dedicated to a different type of music. Every variety of music one can imagine can be found (though if it were my company, I'd add a channel dedicated to Brazilian-like Jazz - e.g. jazzy bosa nova, samba, etc.). Run it through your stereo, and it's a great way to discover new music.
