2000s
In 2001, fans awaited the arrival of a new album, announced as Togetherland. After a protracted postproduction period, the album was cancelled. The official word was that Seal simply did not think it made the grade, although this conflicts with other reports that said the album was turned down by the label because producers felt the album would not be commercially successful. Even so, one single was released from the album; "This Could Be Heaven" was released in the US and featured on The Family Man soundtrack. Since December 2006, Seal has indicated that he has plans to excerpt cuts from Togetherland and make them available for streaming download. Meanwhile, Seal co-wrote and provided vocals for the hit single "My Vision" from Jakatta in 2002. He also recorded a successful duet with French singer Mylène Farmer called "Les Mots" during that same period. Also in 2002, Seal lent his vocals to the song "You Are My Kind", the fourth track on Santana's album Shaman.
In 2003, Seal released his fourth album Seal IV. Although it never achieved the sales figures of either of his first two albums, this release brought him back into the public eye in the United States and continental Europe. Singles from the album include "Waiting for You", "Get It Together" and "Love's Divine"; the latter was released in 2004 and was a big hit in several European countries.
In 2004, a greatest-hits album entitled Best 1991–2004 was released, including a cover of the Bacharach/David classic "Walk On By" and a cover of Echo & the Bunnymen's "Lips Like Sugar". An edition of the album was available that included an extra CD with acoustic versions of some of Seal's hits. Also in 2004, Seal performed shows at the Olympia Theatre in Paris. The show of 6 July 2004 was recorded and released about one year after as a CD/DVD package, simply titled Live in Paris.
In June 2005, Seal recorded a concert which was subsequently released in 2006, entitled One Night to Remember, as a CD/DVD combination. The DVD includes a "making of" documentary in addition to the live performance. Recorded in a historic steel mill, the Altes Kesselhaus ("old boiler house"), in Düsseldorf, Germany, this performance includes a version of Brahms' Lullaby which Seal sings in German and then in English. Unlike earlier recordings in which Seal is accompanied by his band, a full orchestra and choir of 52 musicians accompanies the singer.
System was released in the UK on 12 November 2007 and in the US on 13 November 2007. Seal describes the album as more dance-oriented, apparently a return to the roots of his first album. On the track titled "Wedding Day", Seal sings a duet with his then-wife, model Heidi Klum. The album's first single, "Amazing", was released on 25 September 2007 and nominated for the "Best Male Pop Vocal Performance" Grammy at the 2007 50th Annual Grammy Awards.
Seal performed "Amazing" and the Beatles' "Lucy in the Sky With Diamonds" at the 2007 Royal Variety Performance. Seal also performed "Amazing" at the 2007 Victoria's Secret Fashion Show in December, as well as the duet "Wedding Day" with his wife. Other performers at the 2007 Victoria's Secret Fashion Show include the Spice Girls and will.i.am of the Black Eyed Peas. He appeared on the American Idol season-seven finale, singing with third-place contestant Syesha Mercado.
Seal's sixth studio album, Soul, was released on 3 November 2008 internationally and on 11 November 2008 in the US. It contains 11 soul classics produced by David Foster. The first single was a cover of Sam Cooke's song "A Change Is Gonna Come".
On 14 March 2009, Seal performed a song from the album and coached the participants on the "Top 9-Show" of the sixth season of the German TV show Deutschland sucht den Superstar (German Idol). On 4 December 2009, Hits, a compilation album, was released. It contains two new tracks, "I Am Your Man" and "Thank You".
