According to http://www.shoutcast.com, right at the top of the website is the following:
The future of Internet radio is in immediate danger!
The Copyright Royalty Board in Washington, DC has more than tripled the royalty rates for webcasters and if left unchanged they will *KILL* Internet radio. These exorbitant rates go into effect on May 15, less than a month from now (retroactive to Jan 1, 2006!). Without Congressional action the majority of webcasters will go bankrupt and silent on this date. We need your help. Please take a moment to send a letter to your member of Congress to keep Net radio from being silenced.
Here is a site that describes these royalties more in depth:

It could mean the end to most of the internet radio market...as we know it. Hopefully not, but we shall see.
