www.kurthanson.com also has some information.
I really liked streaming mp3 (still do , as long as it will last) because it has no commercials and plays the music I (.!!) want to hear (easy to pick genre) and often listened to SonaFm , and Bluemars.
I wrote letters some time ago but i dont have large packs of money to wrap it on .
With all this copyprotection crap im even wary off buying new cd's ( i only have my computer cd player) .
Big companies can afford these rates but they will play music they think is popular to atract listeners for their ads :-(
This new law was hard to get for the riaa but i think it will be very much more difficult to get rid of it.
btw the sonafm site says it will soon have a new fax message that you can send to congress.
