Problem: Background: Utada Hikaru (Yu Duo Tian hikaru, born January 19, 1983), who also goes by the mononym Utada (English: ), is a Japanese-American singer-songwriter and producer. Born in New York City to Japanese parents, record producer Utada Teruzane and enka singer Abe Junko, Utada began to write music and lyrics at an early age and often traveled to Tokyo, as a result of her father's job. Eventually, a recording contract with Toshiba-EMI was signed and, under the stage name "Cubic U", Utada released her English-language debut album Precious in early 1998, but was a commercial failure. In the following year, heavily influenced by R&B and dance-pop, her Japanese-language debut First Love was released and became an instant success.
Context: On December 16, 2008, information leaked onto the Internet that Utada's next English-language single, titled "Come Back to Me", would be scheduled for airplay release through U.S. Rhythmic/Crossover and Mainstream formats on February 9 and 10, 2009 respectively via Island Records. The new English album, titled This Is the One, was released on March 14, 2009 in Japan and on May 12, 2009 in the United States. This Is the One debuted at number 1 in Japan on March 13, 2009, the day it was released in Japan, but became Utada's first album not to top the weekly chart since Precious. On March 30, 2009 she appeared on New York City radio station Z-100 (100.3), the largest pop radio program in the U.S., and granted a live on-air interview on the station's Elvis Duran Morning Show, a breakthrough that would lead to a promotional schedule up and through the album's international physical release on May 12. Utada also sang the theme song for the second Evangelion film, Evangelion: 2.0 You Can (Not) Advance. The single was released on June 27, 2009, and is a remix of her previous single, "Beautiful World". The new single is titled Beautiful World -PLANiTb Acoustica Mix-. On October 14, Utada stated that she was writing lyrics that were due on October 15. She also added that some "German magic" would be added to the music. It was revealed that Goetz B, who had previously worked with Utada on her album Ultra Blue was in the process of mixing tracks for her. On November 30, 2009, at Studio Coast, Tokyo, Utada sung a duet of Let It Snow with pop singer Mika.

Problem: Background: Ivan IV Vasilyevich (Russian: Ivan Vasil'evich, tr. Ivan Vasilyevich; 25 August 1530 - 28 March [O.S. 18 March] 1584), commonly known as Ivan the Terrible or Ivan the Fearsome (Russian: Ivan Groznyi , Ivan Grozny; a better translation into modern English
Context: Ivan was the first son of Vasili III and his second wife, Elena Glinskaya, who was of half Serbian and half Lipka Tatar descent, the Glinski clan (nobles based in the Grand Duchy of Lithuania) claiming descent from the Mongol ruler Mamai (1335-1380.) When Ivan was three years old, his father died from an abscess and inflammation on his leg that developed into blood poisoning. Ivan was proclaimed the Grand Prince of Moscow at the request of his father. His mother Elena Glinskaya initially acted as regent, but she died of what many believe to be assassination by poison, in 1538 when Ivan was only eight years old. The regency then alternated between several feuding boyar families fighting for control. According to his own letters, Ivan, along with his younger brother Yuri, often felt neglected and offended by the mighty boyars from the Shuisky and Belsky families. In a letter to Prince Kurbski Ivan remembers, "My brother Iurii, of blessed memory, and me they brought up like vagrants and children of the poorest. What have I suffered for want of garments and food!!" It should be noted, however, that the historian Edward L Keenan has presented compelling reasons to doubt the authenticity of the source in which these quotes are found. On 16 January 1547, at age sixteen, Ivan was crowned with Monomakh's Cap at the Cathedral of the Dormition. He was the first to be crowned as "Tsar of All the Russias", hence claiming the ancestry of Kievan Rus'. Prior to that, rulers of Muscovy were crowned as Grand Princes, although Ivan III the Great, his grandfather, styled himself "tsar" in his correspondence. Two weeks after his coronation, Ivan married his first wife Anastasia Romanovna, a member of the Romanov family, who became the first Russian tsaritsa. By being crowned Tsar, Ivan was sending a message to the world and to Russia: he was now the only supreme ruler of the country, and his will was not to be questioned. "The new title symbolized an assumption of powers equivalent and parallel to those held by former Byzantine Emperor and the Tatar Khan, both known in Russian sources as Tsar. The political effect was to elevate Ivan's position." The new title not only secured the throne, but it also granted Ivan a new dimension of power, one intimately tied to religion. He was now a "divine" leader appointed to enact God's will, as "church texts described Old Testament kings as 'Tsars' and Christ as the Heavenly Tsar." The newly appointed title was then passed on from generation to generation: "succeeding Muscovite rulers ... benefited from the divine nature of the power of the Russian monarch ... crystallized during Ivan's reign."
