The song was a commercial success, charting in Canada, the United States, Australia, Austria, Belgium, Germany, the Netherlands, and New Zealand.

The song was written by Lifehouse's lead singer, Jason Wade, and American singer-songwriter Kevin Rudolf.

[5] "Halfway Gone" was described as a "fun rock-pop [song] that would brighten most people's day" by Alex Lai of Contactmusic.com.

"[8] Ultimate Guitar described the song as "laid-back in its approach", but commended its "hooks and infectious backing 'whoas' in the chorus.

[23] Lifehouse debuted their first live performance of "Halfway Gone" on The Tonight Show with Conan O'Brien on January 19, 2010.

[25] The music video, directed by Frank Borin, was first released on Lifehouse's official website on November 24, 2009.

[28] In the music video, it begins with an out-of-focus view of Wade, seemingly alone, coming up a hill towards the camera.

A group of people (In which one of them is YouTube star, Wendy McColm) pull up in cars and they also lip-synch the song, in addition to performing other activities throughout the video.

[32] Hayley Beck of CWG Magazine gave a positive review of the EP, saying "Honestly I could hear these songs being played in a nightclub, and I definitely never would've imagined myself dancing around to a Lifehouse track!"
