CareerLexy has been featured in songs with many other YG artists, such as Se7en, 1TYM, Jinusean and Wheesung. She was marketed by YG as a hip-hop artist with a little mix of R&B vibe as well. Her debut album, LEXURY (released on October 6, 2003), was fairly well received and with her growing popularity she became a rival with popular singer Lee Hyori for a while. Though her debut album was well received, her second album Lextacy (released on August 26, 2005) didn't achieve as much commercial success when it was released and due to the poor sales it prompted a decision by YG Entertainment to not renew her contract. It was mutually decided that there wouldn't be a re-signing of her contract, but they still wanted to carry out the third album. Titled RUSH, it was released on April 18, 2007 and was on the charts for a few weeks, thanks to her title song "Above The Sky", but the album sales were still not as strong as her debut album.On September 12, 2007 when Yang Hyun Suk announced that Lexy left YG Entertainment, as signing with the agency did not happen, he also revealed that because of that, he felt like he was giving away his younger sister for marriage. Lexy's contract actually ended on October 2006. There has been no problems on money or ill-feelings toward both parties. It was just decided they would go on separate ways.On Lexy's first album, LEXURY, Teddy Park of 1TYM composed the song "Let Me Dance" and Song Baek Kyoung, also from 1TYM, composed the song "Up And Down".After transferring to SB&W Entertainment (Sony BMG & Widethan) Lexy released a new album, THE LEXY, featuring few hip hop artists such as Crown J and VOS.
