If you regularly tune into to an Internet radio station while working at your computer (and we most certainly do), you’ll likely not be able to find any music on your favorite station tomorrow. The regularly scheduled programming of tens of thousands of Internet radio stations will come to a halt tomorrow as part of a national Day of Silence organized by SaveNetRadio.org, a coalition of artists, labels, listeners, and webcasters.

Web radio stations are taking this action to protest the recent 300 percent royalty rate increase for online music webcasters, to raise awareness of the threat these new rates pose to the future of Internet radio and rally support for legislation pending in Congress.

Locally, WAMU.org plans on observing the Day of Silence on its two Internet music channels, explaining:

The new rates would be retroactive to Jan. 1, 2006, and would nearly double the overall cost to WAMU 88.5 for providing a music stream on BluegrassCountry.org this year. With the rates set to increase annually, the station’s overall streaming costs would almost triple by 2010.

We only have a partial list of participants, so if you of any other local stations that have also announced their participation, let us know in the comments.

SaveNetRadio.org is asking people to call their representatives in Congress and urge them to support the The Internet Radio Equality Act, which would overturn the recent decision on raising webcasting fees.
