Today's feminist song comes from an artist that I never would have though of as feminist, at least when I was younger and was super into shaming women for expressing their sexuality.
Can't Hold Us Down by Christina Aguilera featuring Lil' Kim is a fantastic feminist anthem. It deals explicitly with multiple feminist themes, including the condemnation of sexual double standards and giving a big "fuck you" to misogynistic men who don't respect a woman's worth and thinks they should be "seen not heard." It encourages women to "shout out loud" in opposition to men who want us to keep quiet. It also praises the new feminist trend of women calling out misogyny and double standards. Lil' Kim's part also points out how men steal her ideas - something that's been happening for centuries (at least).
Really, the only problem with this song is some implied cissexism. Other than that, it's a perfect addition for any matriarch's feminist playlist.
