Candidate passages:
In a "Rolling Stone" magazine interview, vocalist Chris Martin announced the album's release date and its title, "Viva la Vida", which is a Spanish phrase that translates into English as "long live life".
It takes its name from a painting by Frida Kahlo, an acclaimed 20th century Mexican artist.
The album cover art is an 1830 painting by Eugène Delacroix titled "Liberty Leading the People".
On 10 April 2008, a new journal entry appeared on the band's website announcing the track list and release date, as well as hinting at new tracks to be issued before the album's release.
"Violet Hill" was confirmed as the first single from "Viva la Vida", with a release date of 5 May.
In May 2008, Coldplay featured in an advertisement for Apple's iTunes with the song "Viva la Vida".
The band's official website was updated in late April to reveal the official "Viva la Vida" artwork as well as a free release of the single "Violet Hill", which became available for download for one week from 29 April 2008.
The album was leaked around 5 June and the band decided to make the album available to stream via their Myspace profile from 8:30 pm WEST on 6 June.

In August 2008, Coldplay announced they would be releasing an EP, "Prospekt's March", consisting of unreleased material from the "Viva la Vida" recording sessions.
The album was re-released on 25 November 2008 in a deluxe edition, titled "Viva la Vida - Prospekt's March Edition".
It contains tracks from the original album and "Prospekt's March".
The stage setup for the Viva la Vida Tour consisted of a stripped down main stage and two catwalks; Coldplay also performed amongst audience members at the back of venues in a special acoustic set.
Instead of a giant video screen on-stage, the band opted for six hanging giant lightbulbs that displayed images and closeups.
The band started the tour playing a concert at the Brixton Academy and free shows at Madison Square Garden on 23 June, and ended the tour in Barcelona.
The tour ended on March 2010 at Latin America and consisted of 172 concerts. 
Features and restrictions.
Pricing model.
Since the introduction of the iTunes Store, individual songs were all sold for the same price with no subscription fee (in contrast to most existing online music stores at the time of introduction, which charged a monthly fee for access to their catalog).
Music in the store is in the Advanced Audio Coding (AAC) format, which is the MPEG-4-specified successor to MP3.
Originally, songs were only available with DRM and were encoded at 128 kbit/s.
At the January 2009 Macworld Expo, Apple announced that all iTunes music would be made available without DRM, and encoded at the higher-quality rate of 256 kbit/s.
Previously, this model, known as "iTunes Plus", had been available only for music from EMI and some independent labels.
Previews, ninety seconds in length, are available free, prior to buying a song.
iTunes had the option between fully loading previews before playing, or simply streaming the preview; the former feature was removed with the release of iTunes 8.
Feature length movies and television episodes are also available for purchase.
Movies tend to be priced below a DVD of the same film (price varies, but usually $9.99-$19.99 for new and discounted releases) while television episodes ($1.99 standard definition, $2.99 HD) are approximately double the cost of a song (free, 69¢, 99¢, or $1.29).
Ringtones are $1.29 each, while alert tones are 99¢ each, in comparison.
Finally, some games are available for some models of iPods for various prices, but none as expensive as a feature length film.
In addition, the iTunes Store offers apps, which are applications used for various purposes (games, maps, movie showtimes, etc.)
that are compatible with the iPod Touch, iPhone, and iPad, although some apps are specifically for the iPhone or iPad only.
Some Apps cost money (called "Paid Apps") and some are free (called "Free Apps").
Developers can decide which price they want for apps.
The price, unlike other media on the iTunes store, can vary from being free to being hundreds of dollars.
When someone downloads an App, 70 percent of the purchase goes to the developer(s), and 30 percent goes to Apple.
At the Macworld 2008 keynote, Steve Jobs, who was Apple's CEO at the time, announced iTunes movie rentals.
Movies are available for rent in the iTunes Store on the same day they are released on DVD.
They are only viewable for 24 hours after users begin viewing them.
This feature is not yet available in all countries but it is available in the United States, Mexico, the United Kingdom, Canada and Australia.
There is a weekly promotion in which one to three songs are available to download for free to logged-in users.
Free downloads are available on Tuesdays, and remain free until the following Tuesday, when the store gets refreshed with new content.
Some artists choose to have select songs available for no charge.
This is not available at all iTunes Stores.
Some iTunes television programs have begun the same technique to encourage brand loyalty; although those stay longer.
In fact, the iTunes Store has a "Free TV Episodes" page where free episodes are organized by length, either as "featurettes" (shorter than 15 minutes) or full length episodes (longer than 15 minutes).
Free content can vary from a preview of a show to bonus content to pilot episodes and entire seasons of TV shows (examples of free seasons include HBO's "The Weight of the Nation" and ABC's "Pan-Am").
Some networks, such as ABC and NBC, have their own pages of "Free Season Premieres".
While previously the US iTunes Store has offered as many as three free songs each week (the single of the week, Discovery Download, and Canción de la Semana) in recent years, the store has instead replaced the three afformentioned categories with a unified "Single of the Week" banner, with the week's single being from a new up and coming artist. 
The album was set to be released in December 2010 as a "decade-ender", but was postponed to 2011 since the album was far from finished as Coldplay concluded their Viva la Vida Tour.
Chris Martin and Jonny Buckland mentioned that the album would be released in the latter year.
The iTunes Store let users hear one new song from the album every day the week before until the album was released.
The album was released on 24 October 2011 on CD and on vinyl.
A special edition of the album that includes the CD, digital copy and LP disc along with copies of the bands studio notes, stencils, a poster, a pop up book and stickers was made available on 19 December 2011. 
In October 2006, Coldplay began work on their fourth studio album, "Viva la Vida or Death and All His Friends", with producer Brian Eno.
Taking a break from recording, the band toured Latin America in early 2007, performing in Chile, Argentina, Brazil, and Mexico.
After recording in churches and other venues in Latin America and Spain during their tour, the band said the album would likely reflect Hispanic influence.
The group spent the rest of the year recording with Eno.
Martin described "Viva la Vida" as a new direction for Coldplay: a change from their past three albums, which they have referred to as a "trilogy".
He said the album featured less falsetto as he allowed his voice's lower register to take precedence.
Some songs, such as "Violet Hill", contain distorted guitar riffs and bluesy undertones.
"Violet Hill" was confirmed as the first single, with a radio release date of 29 April 2008.
After the first play, it was freely obtainable from Coldplay's website from 12:15 pm (GMT +0) for one week (achieving two million downloads), until it became commercially available to download on 6 May.
"Violet Hill" entered the UK Top 10, US Top 40 (entering the Top 10 in the Hot Modern Rock Tracks chart) and charted well in the rest of the world.
The title track, "Viva la Vida", was also released exclusively on iTunes.
It became the band's first number one on the "Billboard" Hot 100, and their first UK number one, based on download sales alone.
This was also the first Number One in the UK Singles Chart to be based solely on download sales.
Upon release, "Viva la Vida or Death and All His Friends" topped the album charts worldwide, and was the world's best-selling album of 2008.
It hit number one on the UK album chart, despite having come on the market only three days previously.
In that time, it sold 302,000 copies; the BBC called it "one of the fastest-selling records in UK history".
By the end of June, it had set a new record for most-downloaded album ever.
In October 2008, Coldplay won two "Q" Awards for Best Album for "Viva la Vida or Death and All His Friends" and Best Act in the World Today.

The band followed up "Viva la Vida or Death and All His Friends" with the "Prospekt's March EP", which was released on 21 November 2008.
The EP features tracks from the "Viva la Vida or Death and All His Friends" sessions and, as well as being available on its own, was issued as a bonus disc with later editions of "Viva la Vida or Death and All His Friends".
"Life in Technicolor II" was the only single released from the EP.

On 4 December 2008, Joe Satriani filed a copyright infringement suit against Coldplay in the United States District Court for the Central District of California.
Satriani's suit asserted that the Coldplay song "Viva la Vida" includes "substantial original portions" of the Satriani song "If I Could Fly" from his 2004 album, "Is There Love in Space?".
The Coldplay song in question received two Grammy Awards for "Song of the Year."
The band denied the allegation.
An unspecified settlement was ultimately reached between the parties.

"Viva la Vida" was initially released only with iTunes Store pre-orders of "Viva la Vida or Death and All His Friends" on 7 May 2008 – the "new edit" version of the song – which led to the song's temporary exclusion from the UK Singles Chart.
It was released as a download-only single on 25 May 2008, and a physical CD single in Europe on 29 July 2008 to coincide with the release of the single's music videos.
"Viva la Vida" was well-downloaded in the internet, becoming iTunes' best-selling song of 2008.
