Earthquake (Mýa song)

Trina made a featured guest appearance and lent her voice to the track.

Before being released in the United States, "Earthquake" was originally featured on the Japanese version of K.I.S.S. but removed of respect after the devastating earthquake. "When considering to release it on the U.S. version this fall, again it was a decision I went back and forth on, but ultimately, I think people will understand my decision to release the song, because at the end of the day I think the world is ready to have some fun, and take negative situations and reinvent them into something positive, that we can own, learn from and that bring us together," Mýa told AOL Music of the timing of the song's release. "Sometimes we just need to let loose, let our hair down, come together and shake it like an Earthquake!" the singer added.

Mýa continued, "'Earthquake' is just a really fun song that crowds go wild for when I perform it live and tested it in the clubs.[1]

In an interview with Billboard.com's The Juice, Harrison explained how the collaboration came about with Trina:

Trina and I [initially] worked together for her mixtape, Diamonds Are Forever, and collaborated on a song for her album called 'Can I', and we did a trade-off situation, being that we're both independent," Mýa says. "And I thought she was real appropriate for the record because she comes with that swag."[2]
