Local radio station with the fewest ads?

What local radio stations play the fewest advertisements? Open to any genre of music.

Due to a quirk with my car’s radio/sound system, when the car starts it automatically plays the most recent FM station, and I can’t switch to my phone’s Bluetooth for about 1 minute because it’s slow to connect.

I’m tired of listening to loud, grating ads the moment I start my car since that’s commonly what’s playing on a lot of stations. Any advice? Would enjoy any type of music – not talk radio.
