Despite a plagiarism controversy, G-Dragon, the leader of pop idol group Big Bang, continues to stand out in the local music market with his first solo album.
``Heartbreaker,'' the album's title track, ranked first in various online music charts such as Mnet and Melon as of Thursday.
Other songs on the album, such as ``Breath,'' were among the top 20.
Sales of the album are also on the rise. According to YG Entertainment, G-Dragon's agency, more than 100,000 copies of G-Dragon's album have been sold in just four days since its release.
``We are surprised at the album's sales volume at a time when it is difficult to expect sales of even 30,000 copies,'' a YG official was quoted as saying.
G-Dragon plans to sing ``Heartbreaker'' and ``Breath'' on a music program on SBS-TV on Sunday.
Internet users recently pointed out that ``Heartbreaker'' sounded quite similar to American rapper Flo Rida's ``Right Round.''
G-Dragon, whose Korean name is Kwon Ji-yong, began training under YG Entertainment at the age of 12. After six years of vocal and dance training, he made his debut in 2006 as part of Big Bang.
