You can find better grammar elsewhere on the radio

I was listening to the radio yesterday while running errands. There was an advertisement for Select Stone on 93.5 WRQN. The voice was attempting to be southern with a bit of a twang and the obligatory bad grammar. I lived in North Carolina. There aren't as many people with southern accents as we are led to believe. The obligatory bad grammar: "It don't get no better than that." So by speaking a double-negative you are saying that it does get better. Grammar does get better with practice.
