Correction: By the time your read this American internet radio will be dead.
If this is over the Copyright Royalty Board increases, it will only serve to drive internet radio stations out of the US. The scope of this law only affects broadcasters within the US borders. They have no legal jurisdiction to pass laws affecting broadcasters in any other country.
This will drive many of the broadcasters to 'officially' set up shop in another country, such as Canada and Mexico, where this law applies to nobody.
