Had it not been for Brown's new "Fortune" release, we would have seen a surprise return to No. 1 for Katy Perry, as her "Teenage Dream" set zooms from No. 21 to No. 2 with 80,000 (up 417%) -- and its best sales frame since Christmas of 2010. The set was one of 20 titles the Amazon MP3 store sale priced for 99 cents -- for one day only -- on July 3. (Perry also benefits from buzz earned by the release of her "Part of Me" film, which hit U.S. theaters on July 5.)
