Circus: "The title track is a rampaging monster of a song whose chorus kicks off with a Max Martin-style thump. "I'm the ringleader, I call the shots, I'm a firecracker, I like it hot," Britney sings on the verses. It's been confirmed as the next single and the video's already been shot."
If You Seek Amy: "Britney actually reunites with Max Martin, is 50% glam, 50% rave. The title has nothing to do with a certain Miss Winehouse and makes more sense if you say it quickly... just don't do so in polite company."According to The Sun, a lyric to the offensive track says: "All the boys and all the girls want to if you seek Amy.""A stomping robo pop number with clattering kettle drums and Brit being quite frank about the opinion she holds of herself. "
Out From Under: A "proper, teary-eyed ballad," something that Blackout lacked. "Really quite lovely."Another line: "We tried everything we could try so let's just say goodbye forever.""It's a stirring break-up ballad up there with the best."
