The composition was recorded between July and September 2006 at DFA Studios in New York City. The publicity for "45:33" described it as being designed to accompany jogging workouts, "to reward and push at good intervals of a run." An early statement detailed that the composition had been refined after several runs on the treadmill. James Murphy later admitted that this was entirely a lie on his part, and that he does not actually jog. He stated that he wanted to make a long-form record like E2-E4 by Manuel Göttsching and used the opportunity provided by Nike to do so. The artwork of "45:33" also resembles that of Göttsching's work. Parts of "45:33" were later used on the albumSound of Silver, in particular the track "Someone Great", which appears on "45:33" as an instrumental section later distinguished as track 3. The complete track was also released for registered Nike+ users in late March 2007 as a gift of appreciation when Nike+ logged its 10 millionth mile. The composition was available to be sold by Nike via iTunes for six months. The actual length of the composition is slightly longer than 45:33; the title is instead a reference to the two common vinyl speeds, 45 and 33 RPM. The composition has been described musically as progressive electronic, disco, funk, and synth-pop. For the last series of concerts at Terminal 5 and Madison Square Garden, LCD Soundsystem performed "45:33" in full during the second set, with "Sound of Silver" replacing Part 3. Part 3 was saved until their performance of "Someone Great". On the digital release of the concert, the 45:33 tracks were titled: "45:33 Intro", "You Can't Hide / Shame On You", "Out In Space" and "Ships Talking".

Critical reception
"45:33" received critical acclaim. On the review aggregator website Metacritic, which assigns a weighted average out of 100 points, the album received an average critic score of 86, based on 25 reviews, indicating "universal acclaim". Manuel Göttsching was, however, critical of the composition, despite it being inspired by his own work, stating: "Musically, there is nothing related to E2-E4 – it's just a 'megamix' of his work."
