# In My Head (Jason Derulo song)

"In My Head" is a song by American singer Jason Derulo, released as the second single from his self-titled debut studio album. It was first released on December 10, 2009. "In My Head" peaked at number five on the Billboard Hot 100. Outside of the United States, "In My Head" topped the charts in Australia, Poland, and the United Kingdom, and peaked within the top ten of the charts in several other countries, including Canada, Germany, and New Zealand. The song's official remix has a heavier R&B sound and features rapper Nicki Minaj. Derulo performed the song on the ninth season of American Idol.

## Background

Derulo has explained that "In My Head" was chosen to be released as the second single from the album to show the other side of his debut album. The song is electro-influenced and has a heavier rock feel than the R&B and electronica-influenced "Whatcha Say". He mentioned that the album displays both sides, so "In My Head" was released to introduce his fans to the electronic side of the record. The official remix features Nicki Minaj and was released on March 11, 2010. The song was initially titled "In My Bed", but Derulo and Kelly changed this to "In My Head" at the last minute.

## Chart performance

"In My Head" debuted on the Billboard Hot 100 at number 63 for the week ending December 26, 2009. It has since become Derulo's second song to reach the top 10, peaking at number five.

In Australia, the song peaked at the top of the ARIA Singles Chart, and was the only song to debut at number one in Australia in 2010. It has been certified 7× Platinum in Australia, making it one of the country's best-selling singles of all time.

## Music video

The music video was filmed in late December 2009 and released on January 23, 2010, via YouTube. The video begins in the parking lot of a convenience store, with Derulo leaning on a car with some friends when he eventually spots the female lead (played by Lala Escarzega) leaving the store. Derulo is staring at her (with his debut single "Whatcha Say" playing in the background), and eventually he goes up and talks to her and starts singing to her. The video is an extensive dancing video with Derulo dancing near the car with the female lead, in the occasional breakaways, and far more extensively with two male dancers during the bridge of the song. The music video occasionally breaks away to Derulo's silhouette dancing in the fog. Eventually the girl he is dreaming about has joined him. In the end it is revealed that the entire music video was all in Derulo's head, and the beginning scene is shown again with the female lead exiting the store, heard asking Derulo if they had ever met before. As with the beginning, "Whatcha Say" is also played in the end. The video was directed by Kai Crawford.
