In the episode "Brrap Brrap Pew Pew" (season three, episode six), Diane accidentally announces she is getting an abortion via pop starlet Sextina Aquafina's Twitter account, and gets swept up in talks about the practice. The season four episode "Thoughts and Prayers" took a similar satirical approach towards the frequency of mass shootings and the gun debate in America, after Diane fires a gun for the first time and one of Princess Carolyn's projects get caught in the crossfire, launching a debate on whether or not women should own and use guns. The fifth season has been praised for its handling of sexual harassment and powerful men following the Me Too movement. Emily VanDerWerff wrote that it "just might be the best artistic rumination on #MeToo and an age of terrible men yet." The show also explores Todd Chavez's open asexuality, which is addressed throughout the latter three seasons. In the last episode of the third season, Todd says "I'm not gay... I mean, I don't think I am, but I don't think I'm straight, either. I don't know what I am. I think I might be nothing." In season 6, Todd forms a relationship with a rabbit named Maude, whom he meets on the asexual dating app he created, "All About That Ace." The main title theme was composed by Patrick Carney, drummer for the blues-rock duo The Black Keys, with his uncle Ralph Carney. The main sound, starting at the beginning, is a Roland Jupiter-4 analog synthesizer triggered with a click track in Pro Tools. The ending credits theme "Back in the 90s (BoJack's Theme)" was performed by the indie-pop act Grouplove. Jesse Novak composed the incidental music. In addition, the show has occasionally featured other songs in the closing credits. In season one, Lyla Foy's song "Impossible" appears in the end credits of the seventh episode, "Say Anything"; the Death Grips song "No Love" is used in "Downer Ending", the eleventh episode; and the Rolling Stones song "Wild Horses" and Tegan and Sara's "Closer" in "Later", the first-season finale. The Kevin Morby song "Parade" closed out "Yes And", episode ten of the second season, and the Courtney Barnett song "Avant Gardener" plays during "Out to Sea", the second-season finale. The show features Oberhofer's song "Sea of Dreams" in the fourth episode of the third season, "Fish out of Water", and Nina Simone's cover of Janis Ian's "Stars" in "That Went Well", the last episode of that season.
