"Believe" was written by Dima Bilan and Jim Beanz. It was recorded by Bilan, with production by Beanz and Timbaland. He also recorded a Russian version titled "Все в твоих руках" ("All in your hands"), and a Spanish version titled "Creer".
Later in March 2008, a video was produced for the song. The whole team took part in the production – Dima Bilan, Evgeni Plushenko, Edvin Marton, and Yana Rudkovskaya –Dima Bilan's producer–. The action of the video starts in a hospital where a mother finds out that her son has leukaemia and needs an expensive surgery. Then the action proceeds to a bar where Bilan is watching television and finds out that a child needs help. He immediately calls his producer, Rudkovskaya, and tells her that they have to do something to raise money to help a child survive. They decide to give a charity concert with all the three participants performing. At the end of the video you can see the boy after the surgery. He smiles, gets up from the wheelchair and runs to greet the people who saved his life. Dima, Evgeni, and Edvin meet the boy with presents happy that the money raised at the concert saved a child's life. The video is strongly connected to the song delivering the message that everything is possible in this world if you only believe.

On 20 May 2008, the first semi-final of the Eurovision Song Contest was held in the Belgrade Arena in Belgrade hosted by Radio Television of Serbia (RTS) and broadcast live throughout the continent. Bilan performed "Believe" eighteenth on the evening accompanied by Evgeni Plushenko –skating on artificial ice– and Edvin Marton –playing his Stradivarius violin–, following Romania's "Pe-o margine de lume" by Nico and Vlad and preceding Greece's "Secret Combination" by Kalomira. After the grand final it was revealed that it had received in its semi-final 135 points, placing third in a field of nineteen and qualifying for the final.
On 24 May 2008, the grand final for the Eurovision Song Contest was held. Bilan performed again "Believe" twenty-fourth on the evening, following Serbia's "Oro" by Jelena Tomašević and Bora Dugić and preceding Norway's "Hold On Be Strong" by Maria.
The song won the contest, finishing first with a total of 272 points, becoming the first ever win for Russia, and the fourth for a former Soviet Union country. Dmitriy Medvedev, president of Russia at the time, admitted that he had watched the contest and called right away to congratulate Bilan.
