Firstly sft42 if you have only seen the film I urge you to read the book. I think High Fidelity is a great book and the way it's written means it's easy to see similarities with your own life, I picked it up when staying at a friends house during a particularly messy split up and loved it, ironically enough as in the book I am now back with the person I split up with. I also think this is often the case particularly I find with songs, it's almost as if you want certain songs to be about your life, perhaps it's human nature to look for similarilties like these?
