High Fidelity (1995)

Nick Hornby's first novel, an international bestseller and instantly recognized by critics and readers alike as a classic, helps to explain men to women, and men to men. Rob is good on music: he owns a small record shop and has strong views on what's decent and what isn't. But he's much less good on relationships. In fact, he's not at all sure that he wants to commit himself to anyone. So it's hardly surprising that his girlfriend decides that enough is enough.
