1) They won't stream because somehow, it's not worth their financial while. Don't ask me how, I haven't worked there in many years. I don't see it happening under the current owner, who isn't going anywhere anytime soon.
2) Many radio stations use their air product as the hold music. Call them and ask to be put on hold. Spend your allowance on the cost of the call.
3) You didn't get a reply because the employees who would make decisions about streaming are not computer savvy.
