And she kept at it even after her first single didn't do much. I'm curious to see how radio reacts to her follow-up to "Things a Man Oughta Know," but that might not come for a while, as most stations are still playing the hell out of her big summer hit here in October.
What radio stations say is they don't want a one hit wonder. They want to build careers. So its likely that the major stations have already seen her perform (she's been on tour with Jason Aldean) and have heard at least half of her album. They've heard the next single and have seen the audience response in a live setting. So they may be pre-sold.
I said it takes work for the artist, but it also takes work for the radio station. They have to attend showcases or invite artists to the station. Most of the ones I know promote small shows in area clubs, and invite a group of their regular listeners (either by social media or through their loyal listener club). Those that don't might work with a consultant who does the homework. As I often say, this is not a hobby. It takes a lot of work to be successful.
