The music duo Siria is composed of singer Natalie Horler of Cascada fame, and DJ Manian, known both for his solo work as well as his work within Cascada. The Siria project has had two singles released into the German and Canadian markets featuring the vocals of Natalie Horler. On July 3, 2008, a cover of Mylène Farmer's song Desenchantee was released by Zooland Records featuring a new vocalist.

"Endless Summer" was released as the first single of the Siria project. When it was first released to DJ's in December 2004, it introduced the music style that would prove very successful for the Cascada project with Everytime We Touch in 2005. Initially, fans of Cascada assumed that the group had changed their name to Siria due to legal problems with the name Cascada (they had previously been called Cascade until Kaskade threatened a lawsuit), though it was soon understood that this was just a side project of Manuel Reuter (DJ Manian) and Natalie Horler, without Yanou.

In early 2005, Siria released "I Will Believe It" on the "Endless Summer"/"I Will Believe It" 12" single. There are two mixes of the song. The first is a Euro-Trance version, which is similar to DJ Manian and Natalie's other single Reason released by another one of their projects, Diamond. The other remix is the "Cascada Remix", which has a darker but similar style to the then-recently released Everytime We Touch. The U.S. release of the single comes with eight mixes featuring DJ Lenny B, Solar City and is available through Marian Records, Inc. The single peaked at #23 on Billboard's Hot Dance Club Play chart.

Vladimir Vladimirovich Putin (Russian: Влади́мир Влади́мирович Пу́тин; IPA: [vɫɐˈdʲimʲɪr vɫɐˈdʲimʲɪrəvʲɪtɕ ˈputʲɪn] ( listen); born 7 October 1952) is a Russian politician who has been the President of Russia since 7 May 2012. Putin previously served as President from 2000 to 2008 and as Prime Minister of Russia from 1999 to 2000, and again from 2008 to 2012. Putin also serves as chairman of United Russia and Chairman of the Council of Ministers of the Union of Russia and Belarus. He became acting President on 31 December 1999, when president Boris Yeltsin resigned in a surprising move. Putin won the 2000 presidential election; in 2004 he was re-elected for a second term lasting until 7 May 2008.

Because of constitutionally mandated term limits, Putin was ineligible to run for a third consecutive presidential term. After his successor Dmitry Medvedev won the 2008 presidential election, Putin was nominated by Medvedev to be Russia's Prime Minister; Putin took office on 8 May 2008 and a period of so-called "tandemocracy" followed. In September 2011, Putin and Medvedev agreed he should seek a third, non-consecutive term in the 2012 presidential election, which he won in the first round on 4 March 2012.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
