The song "Just Lust" by Joan Jett and The Blackhearts explores the theme of superficial attraction and physical desire. The lyrics suggest that the singer is infatuated with someone and is drawn to their movements and physical presence. However, they make it clear that what they feel is lust and not genuine love. The chorus repeatedly emphasizes that the relationship is solely based on lust and not any deeper emotional connection. The singer mentions wanting to take the person home and engage in physical intimacy, but they want to make it clear that this does not signify love. The lyrics also communicate a sense of detachment and skepticism. The singer suggests that the other person may mistake their physical desire for love, but the singer's heart is not invested in the relationship. When the person is out of sight, they are out of mind, further emphasizing the lack of emotional attachment. Overall, "Just Lust" explores the concept of temporary, physical attraction and cautions against mistaking it for genuine love.
