I don't know where I first heard about Wilson's book -- probably via Bookforum -- but it's gotten plenty of press, including a mention by James Franco at the Oscars and an interview of Wilson by Stephen Colbert. The concept of the book is seductive: Wilson, a Canadian music critic and avowed Céline-hater, spends a year trying to figure out why she is so popular and what his hatred of her says about himself. I kept away from the book for a little while because I thought it couldn't possibly live up to its premise, and that in all likelihood it was more stunt than analysis. Nonetheless, the premise kept attracting me, because I am fascinated by the concept of taste and I, too, find Dion's music to be the sonic equivalent of a Thomas Kinkade painting.
What makes Wilson's approach so effective and insightful is that it avoids the fanboy defensiveness marring everything from internet discussions to scholarly studies such as Peter Swirski's From Lowbrow to Nobrow
