"Alive" doesn't appear on the film score of Enough, and instead was included as the sole original song on Lopez's first remix album, J to tha L-O! The Remixes (2002).
Music critics were divided on "Alive"; some deemed Lopez's change in musical style to be refreshing, while others felt as if she should stick to the dance arrangements of her previous work.
While the song failed to appear on any national charts, it did reach number two on the US Billboard Dance Music/Club Play Singles chart.
Lopez performed the song live for the first and only time on The Oprah Winfrey Show on May 17, 2002.
Recording music and filming Enough at the same time, Lopez became overworked and had a nervous breakdown. She suffered from a lack of sleep and froze up in her trailer. In 2008, Lopez confessed: "I was like - I don't want to move, I don't want to talk, I don't want to do anything".
