The Party Starts Now is a song by Cadence. It is sung by Cadence and choreographed by many Penguins. It is Cadence's very first single and was once number #1 in the iTunes music store. The full song became available on iTunes on July 17, 2012 . It is used as the theme song for the Make Your Mark: Ultimate Jam.

In the music video itself, Cadence sings her new song, The Party Starts Now, throughout the entire episode, and more Penguins, Puffles, and Famous Penguins come and start dance to it in the Dance Club. Then the lights in the Night Club go out, so Cadence moves the party to the roof, and the dancing continues on, getting even more popular, until the song ends with Cadence saying, "Cadence out." Among the penguins and puffles, Aunt Arctic, Rockhopper, The Four Ninjas, Dubstep, Happy77, Gary and Puffle Handler can be seen. If you look closely, you might find Herbert P.Bear Esquire, who some believe to be the cause of the power outage.

The original song was co-written by Michelle Lewis (China Anne McClain, Lisa Loeb’s Camp Lisa, Raven Symone) and guitarist/ songwriter/producer/composer Dan Petty, two of the artists responsible for music from the hit animated series “Doc McStuffins” on Disney Junior. Penguins were finally allowed to purchase Cadence's new single album on the iTunes Music Store on July 17, 2012. The song itself has gotten positive reviews.

To promote her new single, Cadence held a concert at the Epic Show Stadium with The Penguin Band. She holds a concert there every twenty minutes at the Make Your Mark: Ultimate Jam, and whenever she begins to sing, many penguins will crowd her with heart Emoticons or say "IT'S CADENCE!" Unfortunately, only the first part of the song is sung. It had been said in the Club Penguin Times that Rocky and Cece had helped her prepare for the concert. Rarely, after her performance of the song, Cadence will come Backstage! and greet fans.
