RadioTime is a Microsoft Windows Media Center plugin, which offers visitors the ability to stream over 100,000 radio stations for free with their web browser. Since it's not based on MCML, the plugin should work for both MCE 2005 and Vista MCE. And for the few users who actually have an FM tuner and antenna integrated into your MCE systems, it will even support those.
With RadioTime you can: Find local radio by zip code, browse stations by location, by genre, and by subcategories, Search by: radio station, program name, personality name; Listen to radio, save presets for quick access; Record radio with RedButton, a PC software that works like TiVo for radio.
