"Sad Song" is the lead single by the American rock band The Cars from its 2011 studio album Move Like This. A brief clip of the track was released in December 2010; the full song was released to radio on March 1, 2011.
Exclaim! magazine comments on the song saying "[d]espite the title and lyrics, it doesn't sound particularly sad, as it contains a cheery beat and a catchy mix of synths and guitars". Critics have noted the similarity of "Sad Song" to the band's earlier singles, such as 1978's "My Best Friend's Girl" and 1979's "Let's Go".
