Unfortunately I can't sign this since I'm not a US resident.
I enjoy listening to some webradio stations every now and then, it's a great way to discover good artists and music without having to (illegally) download files. Most of the streams I listen to are European, but it would be a shame to see the American streams destroyed.
Seems like the American love for freedom is only surpassed by it's love for money. However, I'm not sure this will benefit the artists. If I find a good artist from some stream I might buy a cd if like it good enough. If I never heard of it you know I won't buy the cd.
Also, webradio stations from abroad will just get more listeners.
