A radio executive is facing backlash for his comments about limiting air time for female artists in order to increase ratings.

Keith Hill told Country Aircheck Weekly that female country artists are “just not the lettuce in our salad.” He said that Luke Bryan, Blake Shelton, Keith Urban and similar artists are the lettuce, while “the tomatoes of our salad are females.”

“If you want to make ratings in country radio, take females out,” said Hill, who advises stations to limit female artists’ air time to 15 percent.

Martina McBride wrote on Facebook, “I feel like whether or not a song gets airplay should be based on how good the SONG is...not whether it's sung by a male or female. It's kind of like comparing tall artists to short artists, blondes to brunettes, bald guys to guys with hair....what does it matter?”

I want to thank CBS This Morning for having me on today. But there are a few things I forgot to say. Being on live tv...
