YOUR TOP 15 (PLUS TWO): As expected, Katy Perry will debut at #1, giving Steve Barnett’s Capitol Records its first #1 since the exec took the helm late last year. The bow of Perry’s PRISM will best by about 100k her previous release, Teenage Dream, which opened with 192k in August of 2010. TLC’s 20, which came out last week, leaps into the Top 15 after Monday night’s premiere of the VH1 biopic CrazySexyCool; with 4.5 million viewers it’s the highest-rated cable movie of the year, as well as VH1’s biggest original movie ever, according to Bloomberg Businessweek.
