KEXP is great for this - various types of live shows and sets with great DJs. Most of the new music I've discovered over the past 10 years has been from them.
All we really need is a solid system for adding all of the 100k+ internet radio stations to a synthetic radio spectrum that can be easily navigated with a rotary dial just like local radio.
I only listen to FM radio in the car. This has forced me to kinda enjoy Mexican music, cause it's either that or 1980s millennials' nostalgia channels.
