Katy Perry single review 'Part of Me'

Katy Perry is at it again.

The singer owned the Billboard Charts in 2011, becoming the first female ever to have five songs chart at No. 1 from one album, and she has continued that trend into 2012.

Her new song, “Part of Me,” which she debuted during her performance at the Grammy Awards two weeks ago, opened up at No. 1 on the Billboard charts this week, being only the 20th song to start its Billboard run at No. 1.

With production from Dr. Luke and writing done in large part by Bonnie Mckee, both of whom helped churn out hits like "California Gurls," "Teenage Dream," and "Last Friday Night (T.G.I.F.)," it is no secret that this song is an instant success.

It is a breakup anthem, with lyrics that were reportedly rewritten from earlier versions so that the song serves as a direct shot to soon-to-be ex-husband Russell Brand, who she was married to for a year.

“This is the part of me, that you’re never gonna ever take away from me,” Perry sings, seemingly to Brand himself, in the chorus.

With a "California Gurls"-like sound, the song is very alive, with an upbeat tempo that will spawn many plays in the clubs, while being a fan-favorite for Perry to perform at concerts.

What makes this song stand out from her other hits is the directness and substance of the lyrics. Instead of painting the usual fantasy land world where everything is great and the world is all smiles, Perry shows another side. She gets in touch with pain and human emotion that comes from a negative experience, although she does not fail to overcome it and come out a hero, not only to herself, but to females all around the world.

Perry announced through Twitter that all proceeds from the song will go to MusiCares, a charity for the arts.

“Part of Me ” serves as the first official single from the re-release of Teenage Dream, entitled Teenage Dream: The Complete Confection, to be released on March 27.
