Tribes to skirt webcast rules?

Native American Tribes Could Webcast Under Their Own RulesNative American reservations allow gambling in states that normally ban it, and sell cheap tobacco that's not subject to taxes paid elsewhere in the country, due to the "limited sovereignty" granted them by the Supreme Court.

But what about digital music? Would the same rules apply, enabling tribes to set up webcasting services without forking over exorbitant royalties to SoundExchange or sell songs for ten cents a pop?
