Modern K-pop is marked by its use of English phrases. Jin Dal Yong of "Popular Music and Society " wrote that the usage may be influenced by "Korean-Americans and/or Koreans who studied in the U.S. take full advantage of their English fluency and cultural resources that are not found commonly among those who were raised and educated in Korea." Korean pop music from singers or groups who are Korean-American such as Fly to the Sky, g.o.d, Rich, Yoo Seung-jun, and Drunken Tiger has both American style and English lyrics. These Korean-American singers' music has a different style from common Korean music, which attracts the interest of young people. Increasingly, foreign songwriters and producers are employed to work on songs for K-pop idols, such as will.i.am and Sean Garrett. Foreign musicians, including rappers such as Akon, Kanye West, Ludacris, and Snoop Dogg, have also featured on K-pop songs.
