Our weekly list of the fastest growing applications on Facebook takes on a different look now that the site has changed how it counts active users. The previous tally included everyone who grants permission to an application regardless of whether they’ve gone on to use the app, while the new statistics exclude those who’ve permitted but haven’t actually used the application.

Page tabs take over in the first week of these changes, and we also have quite a few noisy musician tools for both users and bands making the cut.
