 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).
