internet radio in car ?

ok as most of you would allready know ,i am into my
Papua New Guineaian folk music .
so ,is there a way to listen to internet radios in my car without too
much hassle ? what sort of equipment and
mobile internet subscription would be needed for this ?

I guess buying a DAB radio would work IF you are in an area with DAB... Can't think of any other way that would work unless you want to spend a lot of money on a setup that could do this.
