The Cosmos Rocks

The band entered Roger Taylor's Priory studio in late 2006, having completed the American leg of a world tour. Sessions were initially scheduled around Rodgers' other touring commitments. On tour, the band had debuted a new song, "Take Love", although it did not make the album (Rodgers would later record his own version of the song for his 2023 solo album Midnight Rose). On his solo tour, Rodgers debuted songs such as "Warboys" and "Voodoo".

John Deacon's retirement meant that bass duties were shared between Rodgers and May.

The first single, "Say It's Not True" was released nine months before the album. The second, "C-lebrity" was previewed on Al Murray's Happy Hour in April, five months before the album.

The album's release came 17 years after the death in 1991 of former Queen singer Freddie Mercury.

"It had some great stuff on it," Taylor recalled. "I just think that Paul's more blues and soul, one of our favourite singers, ever, but, when it boils down to it, he wasn't the perfect frontman for us. I felt the album was badly promoted by EMI, who were falling to bits at the time. We were on tour in Europe, and I went into record stores and we weren't in them. And I remember being furious, thinking, 'Why did we make this fucking record?'"

May later recalled: "We spent a huge amount of time making that album with Paul Rodgers, going through quite a lot of pain, and I don't think it made the slightest dent on public consciousness. So I would be cautious about being in a recording group called Queen without Freddie."

Three singles were released from the album:

• "Say It's Not True" was the lead single from the album, released in the UK on 31 December 2007; it reached #90 in the British charts although had been available as free download for some time. Its video features many clips of the suffering in South Africa as well as clips from Nelson Mandela's 46664 concerts. The single was released for the 46664 charity, with all proceeds being donated there.
• "C-lebrity" was released as the album's second single on 8 September 2008, reaching number 33 on the UK Singles Chart. Its B-side was a recording of "Fire and Water" live in Japan.
• "We Believe" was released as a promo single in Italy, and reached number 4 in the Virgin radio charts. It was edited down from its original 6-minute album version to less than 4 minutes.

The Cosmos Rocks received mixed reviews. According to critic review aggregator Metacritic, the album received an average review score of 42/100, indicating "Mixed or average reviews". Alexis Petridis of The Guardian gave it two out of five stars, stating, "the lyrics were stupid, trite, a bit offensive and bound to have an undermining effect on whatever musical efforts they put behind it". Conversely, PopMatters gave it a 7/10 review, stating, "Paul Rodgers breathes new life into Queen, while still keeping the band's tremendous legacy intact as they soldier forth with new material into the 21st century". Mojo gave it three stars, stating, "Occasionally they stumble, as on the clunky 'Warboys.' But with Rodgers imperious, Queen's second coming is vindicated".

The "Rock the Cosmos Tour" began in September 2008 to promote the release of this album. The opening date was recorded for a DVD release, and was broadcast across digital video theatres across the United States on 6 November 2008 under the title "Let the Cosmos Rock". The tour included one of the largest open-air concerts in Kharkiv, Ukraine, which garnered 350,000 people. Over the course of the tour, Queen played to just short of a million viewers.
