Fifteen years after the release of her debut album, Animal, Kesha is feeling nostalgic. In an Instagram post on Sunday (Jan. 5), the singer looked back on the making of the 2010 LP that made her a star and featured such beloved tracks as “Your Love Is My Drug,” “Tik Tok,” “Blah Blah Blah” and “Party at a Rich Dude’s House.”

“I spent my whole life learning the art of songwriting from my mom, an iconic songwriter herself, so when Animal came out, it was a culmination of the sounds of growing up, the sounds of falling in love, heartbreak, the sounds of coming of age, and I had no idea what these songs would open up for me and what kind of life I would be creating for myself just by putting these songs out in the world,” Kesha wrote, giving props to her mom, Pebe Sebert, a Nashville songwriter known for co-writing the 1980 Dolly Parton track “Old Flames Can’t Hold a Candle to You.”

“I’m so happy I did, and so happy you’ve connected to it the way that you have, and continue to do so,” she added, noting that the album’s debut hit, “Tik Tok,” had its biggest streaming day ever on Spotify last week following her set on Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest. “Just goes to show that we all go through these same pivotal feelings and emotions growing up. I’m so happy to have grown up with all of you. Happy anniversary Animal. I had no idea you were that b–ch. But turns out you totally are.”

In an accompanying video, a then 22-year-old Kesha is asked what she thinks about how happy Animal is making her fans. “The only reason I made this record is to make kids have fun and have dance parties and inspire people to just be happy,” she says, her face covered in glitter in the clip that ends with a montage of looks and iconic moments from that era. “This whole is just kind of a very youthful, irreverent record. And I want it to be one of those records that you just put on and no matter what you’re doing or where you are it makes you happy.”

The singer has released the songs “Delusional” and “Joyride” as the first singles from her upcoming, as-yet-untitled sixth album, which will be the first release from her Kesha Records imprint.
