What are the motifs in High Fidelity by Nick Hornby?

Popular Culture is a recurring idea in the book. Hornby continuously litters his book with references to popular culture. Even his similes and metaphors revolve around films, music, or television. For example, when Laura tells him their breakup has nothing to do with anyone else, he states Celia Johnson would of probably of said the same to her husband if she had gone off with Trevor Howard at the end of Brief Encounter.
