Questions best left unanswered

So, I was workin, see? and the manager, this one dude, put the radio on country.
Alright. I don't really mind. Moving on.

This one song came on that went something like this;

nothin' on but the radio.

the soft music that'll soothe the soul.

You and me and the lights, down... low.

nothin' on but the radio.

Now, here's my question.

What does that mean?

does he mean the only thing "turned on" is the radio, and his significant other no longer causes to awaken in him carnal passions of reproduction?

does he mean they tried to watch TV, but there was nothing on, so they're listening to the radio?

does he mean they don't have any music, so they have to listen to the radio?

or, and here's my theory,

does he mean they're both naked listening to the radio?


That's why I love country, there's so many layers of meaning...
