One might consider using an appropriate app on a smartphone that is Bluetooth-paired or otherwise connected to a car radio.
Very large selection of musical and other genres with few to no commercials, good S/N, and no fading wherever you are as long as you can connect to the Internet.
It was Brooce MICRO1700 over a year ago who reported listening to KDX Worldround Radio while riding in a car in Hartford, Connecticut.
He did this with some kind of a cell phone arrangement and perhaps an app of some kind.
It's absolutely an avenue for part 15ers to explore.
Listening to streaming radio in the car has been quite common for quite some time.
Just about every car in the last 10 years has a way to connect audio from an external source to the car stereo system. Be it a simple cord that plugs in to the headphone jack of a phone, tablet, computer, etc and plugs in on the other end to the car system. Or something more high tech such as bluetooth, USB or other connection. Heck newer cars with systems that interface via bluetooth or USB allow operating the streaming device (phone, tablet, etc..) through the cars dashboard so you can even work it, select it, change stations, etc on the car radio as if you were listening to a regular station. In both my wifes car and my car, our iphones automatically connect via bluetooth when we get in the car. If we want to listen to a streaming station we just punch it up on the dash like choosing any other input -- AM/FM/Satellite/CD/Jukebox (my car has a built in hard drive that I've loaded thousands of songs into that punch up right on the dash) or external/USB etc. We run the streaming phones apps from the dash. Her phone can stay in her purse. Mine just sits there in the cup holder. This technology has been around for a while. There are hundreds of thousands of streaming stations available through the various sources, not to mention all the commercial broadcasters who stream!
Heck, even back in the 80's you could buy a fake cassette tape that would go into your cars tape deck like a regular cassette, except it had no tape, but a cord with a 1/8" mini plug that could plug into your portable CD player so you could listen to CD's long before CD players were available for cars -- in fact, you can use one of these to play your phone, etc into your old cars cassette deck by plugging it into the headphone jack.
Assuming you have a suitable data plan and decent cell coverage you can drive around listening ti virtually every streaming station anywhere, be it another country, state, town, etc. if it's streaming and you have a cell connection you can listen in your car like it's regular radio. You can of course also listen at home in your computer, and if your computer sound is connected to your stereo it's like listening to regular radio.
I listen to WREN, a streaming only station in Topeka all the time in my car, just like regular radio. We will drive from here in northern Minnesota all the way to Topeka to visit my Son, listening to WREN's stream all the way with no dropouts.
If your Part 15 station is streaming, anyone can listen via internet on any device connected to the internet, just about anywhere, and through their stereo system.

At last night's Blare OnAir LIVE Show for the 5th Saturday of September from the TeamSpeak Open Room there was mention made of KDX Worldround Radio now webcasting at 8 Kilo-bits-per second.
This was questioned by one of the quests who asked. "Are you sure you mean Kilo bits? Don't you mean Kilobytes?"
I (Carl Blare) explained that I'd previously said "kilobytes" but a member of these forums corrected me and explained that it is Kilobits.
To settle the matter we reference Wikipedia:
There. Does that clear things up?

Uh... our KDX Encoder says "8000 kbps".
That's probably why 8 kbps was questioned....
But, a thousand thousand?
Bits per second.
