Don't you bitches start stanning for it now that it's found success
"Three Bells" was more impressive in a way because it had 11 weeks at the top of radio play but, then again, that was during the reign of payola. The fact that "Girl Crush" hasn't hit #1 yet on Country Radio and will most likely not hit #1 for more than a week or so
They need to crossover to Pop/HAC and start pushing it on bigger platforms. It could be a much, much bigger hit if they did so.
The song is phenomenal
