Hope it does well, but tbh, she's just too country for country radio.
Her music is real, honest and has mainly traditional real country production which is the complete opposite of what Country radio is playing. If she wrote a song about dirt roads, tailgates, drinking beer and being redneck crazy and have a generic rock/hip hop leaning production with flourishes of banjo she may have a chance at having a hit single
Let's hope her record label gets behind this song and gets Kacey some decent promo and get those stations to play Dime Store Cowgirl.
