AM is good for people who drive a lot. You get tired of hearing the same songs over and over on regular radio. AM has lots of talk radio. But of course know we have SIRRUS radio so much more to choice from.
Only if I want to be bored or hear the noon news while sitting in the car. The few AM stations that are accessible around here are either talk radio or spanish.
99% of what I listen too on the radio is AM. I get unbiased news reports and talk shows from the local stations. Most of the music played on FM stations here can be used as compost. :)
