Jang Yun-jeong (born February 16, 1980) is a semi-trot singer. Debuting in 1999, she exploded into fame at the beginning of 2005 with her single “Eomeona!” (“어머나!”, an exclamation close in meaning to “Oh my goodness!”). Although in her 20s, she has decided to stick with a genre mainly appealing to older Koreans and has parlayed that into continued success, with five full albums (the latest one in June 2010) and two “half” albums. Because of her age and her popularity, she has been able to play in both the younger K-Pop shows and the older trot shows. She is currently one of the MCs on SBS’s Challenge 1000 Songs.
