Almost every high schooler knows “TiK ToK” by Kesha, whether it’s played in locker rooms, friends’ houses or just as a throwback to the singer’s hit 2009 record.

The song sold over 14 million copies, and was on the top charts in 11 countries, according to a CBS news article.

“TiK ToK” was produced by Dr. Luke, with whom Kesha signed a record deal in 2005, at 18 years old. She is now 30 years old.

Under Dr. Luke’s label Kesha released the hit song “Timber,” as well as the album’s:  “Warrior” and “Animal.” Dr. Luke also helped produce songs for artists like Katy Perry, Brittany Spears and countless others.

In Oct. 2014, Kesha sued Dr. Luke under the accusation of rape. A series of counter lawsuits followed, eventually leading to Kesha suing Sony for release from her label. The request was denied.

Kesha has since removed the dollar sign from her name. If that doesn’t reflect her increased maturity, then her new album certainly does.

In 2017, after four years without releasing any music, Kesha put out an album that appears to reflect on her struggle with Dr. Luke and reflect a positive attitude towards the future.

The album has topped the Billboard 200, and for good reason, too.

“Praying,” the album’s hit song, is simple and centered on a piano.

Kesha comments on someone who’s done her wrong, saying she hopes they will recognize their actions, and the only thing they can do to do is start “praying.” This appears to be a comment on her toxic relationship with Dr. Luke.

The music video made to accompany the song promotes her journey to self-actualization. She starts off the video as a seemingly lifeless body in a colorless landscape, and transitions to a radiant colorful setting. Throughout the video, Kesha represents the process of forgiveness and healing.

Although “Praying” is the top single, “Rainbow,” is equally, if not more, made for success.

Kesha promotes self-love through “Rainbow” as she gives advice to “put those colors on and come and paint the world with me tonight.”

The simple piano chords and orchestral sounds that accompany the song make it easy to focus on the uplifting lyrics.

Both “Rainbow” and “Praying” showcase Kesha’s loving, more forgiving side, but she lets listeners know that she is not to mess with in “Hunt You Down” and “Woman.”

Kesha’s ability to showcase her multi-faceted styles and moods does not stop there.

The singer employs both pop, rock, and folk-based songs, showing the depth and capacity of her style when she has the freedom to express it.

“Rainbow,” has given Kesha the opportunity to reach past her traditional pop-centric auto-tuned sound, and express relatable sentiments through a variety of styles.
