"Do You Realize??" is a song by The Flaming Lips, released as the first single from their 2002 album Yoshimi Battles the Pink Robots. It is widely considered to be one of the group's most accessible and popular songs. It reached #32 in the UK Singles Chart and was adopted as the Official Rock Song of Oklahoma from 2009 to April 2013. The song was ranked #31 on Rolling Stone's 100 Best Songs of the 2000s.

In an interview with Mojo, Coyne revealed that during the recording of Yoshimi..., band member Steven Drozd was trying to kick a heroin addiction. When they took breaks from playing, Drozd would have a really tough time with his withdrawal. Listening to him cry, and with the death of his father in mind, Coyne wrote "Do You Realize??".

Wayne Coyne, commenting on "Do You Realize??" said, "Whenever I analyze the scientific realities of what it means to be living here on Earth – in this galaxy – spinning around the sun – flying through space – a terror shock seizes me!!! I'm reminded once again of how precarious our whole existence is..."

"Syrtis Major" and "Xanthe Terra" are instrumental pieces intended to be taken from the forthcoming Christmas on Mars soundtrack.

In March 2009 "Do You Realize??" was announced as the official state rock song of Oklahoma, after winning an on-line vote among ten finalists as authorized by the Oklahoma state legislature: out of 21,000 votes cast, nearly 51% were for "Do You Realize??" The Oklahoma Senate approved this choice unanimously. However, on 23 April 2009, a vote in the Oklahoma House of Representatives fell three votes short of the 51 votes necessary to ratify the resolution: one Republican state legislator attacked the band for its use of offensive language, while another said he opposed the song because band member Michael Ivins had worn a red T-shirt with a yellow sickle and hammer during a previous appearance by the band. Democratic Governor Brad Henry subsequently announced that he would issue an executive order in lieu of the resolution rejected by the Oklahoma House. It was revealed in 2013 that Republican Governor Mary Fallin removed the song's designation as the Official Rock Song of Oklahoma by not renewing Brad Henry's executive order upon taking office in 2011.
