Rock on. And on.

In the Department of Unsurprising News: Disney is already preparing a sequel to "Camp Rock." Knew we hadn't seen the last of that one. The ratings for the Disney Channel original movie's three-fer premiere -- Friday night on the Disney Channel, Saturday night on ABC, Sunday night on ABC family -- were enough to make a mouseketeer cheer. Among the stats, according to ABC: More than 21 million U.S. viewers have seen the movie so far; the Disney Channel premiere was the most-watched cable entertainment show this year, and was the week's number-one show for teens and tweens.

Also, a song stickiness update: I spoke too soon in my review. Demi Lovato's "This is me" anthem did wind up stuck in my head for the bulk of the weekend. Damn you, Disney.
