Granados, a 25-year-old atomweight, explained that Kesha's lyrics get on her nerves and that her voice is like fingernails scraping against a chalkboard.
"Her voice is annoying and she says the stupidest things in her songs," Granados said. "Unfortunately, I know all the words because I hear her songs everywhere."
Granados, who is riding a four-fight win streak, hopes to use her anger towards Kesha by shifting the focus of the hostility to her upcoming opponent inside the cage.
Granados fights Sarah Lagerstrom on March 23 at the American Bank Center in Corpus Christi, Texas, under the XCP/ ABG Promotions banner.
"I know that I am taller than my opponent, which is weird because I'm not too tall myself," Granados said. " Height will definitely play a factor. I'm pretty strong for my size and I'll have the reach and strength advantage."
Granados, who remains undefeated after racking up victories over tough contenders such as Stephanie Alba and Jordan McDonald, is perhaps one victory away from earning a spot within the Invicta FC ranks.
"Of course I want to fight for that Invicta FC atomweight belt someday," she said. "I'll fight whoever has it."
Granados is part of a fast-growing women's MMA scene in Texas, a state that has spawned such talent as Jordan Nicole Gaza and Amber Stautzenberger, among others.
"The MMA scene is definitely growing in Texas," Granados said. "There are so many promotions popping up and its such an awesome thing that more fighters are getting opportunities to display their hard work in the cage with such awesome fans. Texans are the most awesome fans."
