This song deals with Mann's recurring themes of alienation, uncertainty, and feeling stuck. She analyzes human nature and finds it comes up short: "People are tricky you can't afford to show. Anything risky anything they don't know. The moment you try, kiss it goodbye." Despite its pessimism, "It's Not" is a kind of love song.
The track was used on the popular 1990s teenage drama Dawson's Creek.
Until December 5, 1998, a song had to be issued as a single to make the Hot 100. Aaliyah's "Try Again" was the first tune to top the chart based on airplay alone, without any sales figures being included.
