Are Americans ready to pay $10 a month to listen to radio? Two satellite radio companies hope so. So what’s wrong with conventional radio? Just about everything, the companies say – annoyances like “advertising, the limited reach of AM and FM signals, and, most of all, playlists confined to a small number of heavily promoted singers and groups.” So what’s better about satellite radio? The “chance to hear unsigned bands, live music, seldom-heard cuts from well-known artists and genres of music that have no home today on the AM and FM radio dials, like the electronica that shows up only in clubs and car commercials.”
