Till the World Ends
On one level a response to Gaga and the general dance pop-ification of the charts, some of Britney's seventh album is gonna sound overly familiar: "Till the World Ends," for example, has co-writer Ke$ha written all over it and will.i.am cut "Big Fat Bass" sounds like bland Black Eyed Peas. But listen up, kids: This here's a house Mama Brit built. And she finally sounds comfortable in it -- enough to try some experimental stuff, like the singsong-strange "How I Roll." No more menage-a-messes, no stripper poles: Britney's grown up and ready to relax into life as a sexy, serious dance club grand dame.
