A few days ago, Kesha highlighted the 15th anniversary of her song “TiK ToK” by noting that it had its biggest streaming day ever after she performed it on Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest. Now she’s marking another milestone: the 15th anniversary of the song’s parent album, Animal, which was released on Jan. 5, 2010.

She wrote on Instagram, “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.”

She continued, “I’m so happy I did, and so happy you’ve connected to it the way that you have, and continue to do so. 15 years later, TiK ToK had its biggest streaming day just a few days ago. 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.”

Kesha concluded, “Happy anniversary Animal. I had no idea you were that b****. But turns out you totally are.”

In addition to “TiK ToK,” Animal also spawned the singles “Blah Blah Blah,” “Your Love Is My Drug” and “Take It Off.”
