"Sex on the Radio" is a song performed by the American band Good Charlotte, taken from their fifth studio album Cardiology. It was released as the second single on December 2010, only in Australia and New Zealand. It was written by the band brothers Benji & Joel Madden, with additional writing from Sam Hollander and Dave Katz, with production by the two latter. The song is a pop punk track and talks about all the girls out there who make boys want to start bands and go on tour. It charted inside the top-thirty on the ARIA Singles Chart. The song received mixed reviews from music critics, some thought it was a lively and funny track, others thought it's "cheesy" and that it shouldn't be on the album. A music video was made for the track, in which the band walks the street and ask people what they think of the song.
