I think those rates are for the broadcast stations' internet feeds as opposed to the stations' over the air broadcasts.
Then there is confusion on whether the royalties being paid are for the writers or the performers. As I understand it, broadcast stations have to pay royalties to the writers but not to the performers because the performers are supposed to get increased sales from air play.
In my opinion the rate should be the same no matter what the medium is. The only difficulty is how to handle internet broadcasts where you can track how many people are receiving the station at any time vs. broadcast or satellite where you get no feedback from receivers.
