I don't know what this third song is. My baby daughter enjoys twiddling the knobs on the radio, and with the low quality of the selections thus far, I'm not inclined to spoil her fun.
It's interesting that, while pre-AAA era sets are now chock full of forgotten AM radio hits, there appears to be no need for that type of song during years after the AAA format had come into bloom. There's already a comfortable groove there for the corporate programmers, so why mess with a good thing?
