Does it count those instances where my Ford randomly plays FM radio (sometimes even randomly AM) before I managed to connect BT/Carplay or if that either of those happen to disconnect?

Because that's about the limit of my usage of any terrestrial radio.

You may listen more than you think. Also counted is in-store (and in-restaurant) listening. That's the main reason why so many stations go with all-Christmas music formats.

Most independently owned retail and eating establishments also qualify for a copyright infringement exemption if they play music originated by a radio or television broadcast station licensed by the FCC [1].
