Carl Wilson of Canada's Globe and Mail newspaper did what other music critics might find unfathomable: He listened to Celine Dion. A lot. In the book Let's Talk About Love: A Journey to the End of Taste, Wilson explores the idea of a "guilty displeasure": something we're quick to dismiss because, well, "it's just not me." We find out what Wilson learned from his ordeal -- and if he changed his mind about Dion.

Tell us: What's your "guilty displeasure?" Do you have a music-snob sin to confess?
