Can you name the nine top-selling film soundtracks in U.S. history (per the RIAA, as of Feb 2010)? We were going to ask you for the top ten, but since O Brother Where Art Thou and Grease are tied for tenth, let's see if you can name the nine soundtracks to sell more than those two. We're just looking for the names of the movies. You've got three minutes. Good luck!
