The song was released as the second single from Hilton's upcoming second studio album on July 8, 2014, by Cash Money Records.
Hilton promoted "Come Alive" on Tuesday, July 15, sharing links to the music video and thanking fans for their support via Twitter.
Robbie Daw of Idolator contended, "Come Alive" lives up to its title, as it offers a more mature aesthetic than previous Hilton offerings - and, in all seriousness, she's also showing growth as a vocalist this time around."
Lucas Villa of AXS commended Hilton's serious approach to music, writing, "she puts herself in the pop star lane once again with this dreamy slice of electronica."
Elizabeth Freda of E! Online remarked the video as "insanely amazing " in her review, and then went on to list what she called "The Twelve Greatest Moments " of the video, some of the things she praised in the video included Paris' choice of clothing and the scenery.
