It was issued in the United States on April 10, 2012 as a digital download by Nettwerk and Unfiltered Records.

In Matt Collar's AllMusic description of the track, he stated that it is a "more detached electronica" song with "a slick if still airy mix of melodic guitar pop".

John Bergstrom of PopMatters enjoyed "Lost in the Sun", but preferred Ivy's "World Without You" more.
