Meaning of "Cornerstone" by Arctic Monkeys

The lyrics of "Cornerstone" by Arctic Monkeys explore themes of loss, longing, and the blurred lines between reality and imagination. The speaker's futile search for a woman who seems to constantly elude him represents a deep yearning for connection and a struggle to come to terms with the absence of someone important. The repeated encounters with women who resemble the object of his desire highlight the ways in which memories and wishes can distort perceptions of reality. Ultimately, the realization that he may have fabricated the woman he's searching for speaks to the complexities of grief and the ways in which we hold on to the past.
