What Now nowhere to be found or did you not include its numbers because it's her current single?
Right now only 2 of the T25 country songs are female-led - both of them by a solo The Voice winner.
Urban is either better or worse depending on how you count it - there are 3, but 2 of them feature a dude, leaving just apparent Urban Queen Lorde as a female-only song. She also has the only female-only song in the Rhythmic T25. And the only song by a (primarily/) female artist in the Alternative T25.
