This is a book of essays about songs that have particularly interested Hornby at various points of his life. The essays may not concern the song directly, but are sometimes about what that song may remind him of, or of feelings or events that that song is forever linked to in his mind.
It’s an interesting format. I didn’t know all of the songs, but I can definitely identify with having songs take on a whole other meaning, based on where you were when you first heard it (or what you were doing the summer it was overplayed on the radio). I suppose this format may not be for everyone, but if you love music, you can probably appreciate this book.
