Artist names, song titles, and lyrics have exhibited a significant growth in the usage of English words. No singers in the top fifty charts in 1990 had English in their names: people who worked in the Korean music industry viewed using Korean names as standard. In 1995, most popular singers such as Kim Gun-mo, Park Mi-kyung, Park Jin-young, Lee Seung-chul, and Byun Jin-sub still used Korean names, but fourteen of the singers and groups in the top fifty used English names, including DJ DOC, 015B, Piano, and Solid. After the 1997 financial crisis, the government stopped censoring English lyrics and Korea started to have a boom in English. Since the late 1990s, English usage in singers' names, song titles, and lyrics has grown quickly. Seventeen singers in the top fifty charts used English names in 2000, and thirty-one did so in 2005. In 2010, forty-one singers used English names among the top fifty songs, but usually three or four singers and groups had more than one or two songs on the chart simultaneously. Korean names (e.g. Baek Ji-young, Seo In-young, and Huh Gak) are seen less frequently, and many K-pop singers have English names (e.g. IU, Sistar, T-ara, GD & TOP, Beast, and After School). Notably, until the early 1990s, musicians with English names would transliterate them into hangul, but now singers would use English names written with the Roman alphabet. In 1995, the percentage of song titles using English in the top 50 charts was 8%. This fluctuated between 30% in 2000, 18% in 2005, and 44% in 2010. An example of a Korean song with a large proportion of English lyrics is Kara's "Jumping", which was released at the same time in both Korea and Japan to much success.
