Is music really getting louder and dumber? A new Spanish study analyzing pop music over the past half-century claims songs have gotten louder and less musically complex. Our crack team digs into the merits of the study and the media attention it has received: Carl Wilson, Globe and Mail editor, and author of "Let's Talk About Love: A Journey To The End of Taste". Rob Bowman, York University Professor of Ethnomusicology, and author of "Soulsville, USA." And Maura Johnston, music editor of The Village Voice in New York.
