The album opens with the first single "Gimme More", a dance-pop and electropop song. The song opens with a spoken intro in which Spears says the line "It's Britney, bitch". While the lyrics appear to be about dance and sex, they are actually about the media's fascination with her private life, as noted in the lines "Cameras are flashin' while we're dirty dancin' / They keep watchin', keep watchin'". The next song and second single, "Piece of Me" runs through a down-tempo dance beat and consists of over-the-top vocal distortions, causing a split sound effect and making it difficult to discern which voice is Spears'. It talks about fame and is written like a biography retelling her mishaps, while she sings in a nearly spoken manner. The third track of the album, "Radar", is an electropop and Euro disco song which features distorted synthesizers emulating sonar pulses, that received comparisons to those of Soft Cell's "Tainted Love" (1981). In the lyrics, Spears lets the subject know he is on her radar, while she lists the qualities the man has.
