High Quality Content by WIKIPEDIA articles! "Radar" is a song by American recording artist Britney Spears. The song was recorded in late 2006 in New York City, produced and co-written by Bloodshy & Avant and The Clutch. Musically, "Radar" is an uptempo electropop song that features varied instrumentation, with a high usage of synthesizers. The lyrics of the song refer to an attraction between the protagonist and a man, while she wonders if he knows what she is feeling. "Radar" was first included on her fifth studio album, Blackout, and received mostly positive reviews from critics. The song proved to be successful on airplay charts, and it was planned to release it as the album's fourth single; however, the release was cancelled. The song was later included as a bonus track on her sixth studio album Circus, and was released on June 23, 2009 by Jive Records as the fourth and final single from that album. The track performed poorly on the charts and did not manage to enter the top forty in most countries.
