Four popular Korean solo singers -- Rain, Se7en, Lee Hyo-lee, and BoA -- will come back to the Korean pop scene. Netizens call them the representative singers for Korean pop in the 2000s, and they are overjoyed at their return. Rain and Lee Hyo-lee will come back after breaks of 18 months and 20 months, respectively. Se7en and BoA, who have focused on the American music industry up to now, return to the Korean music scene after breaks of three years and five years, respectively. The return of these famous solo singers is drawing people's attention because girls groups and new idol groups gained popularity last year.

In addition, Rain will release a mini album containing 4 or 5 songs in late April. He did not record a new album because he played the protagonist in his first Hollywood film, "Ninja Assassin", and helped the group Mblaq debut in 2009. His agency, J Tune Entertainment, said, "We have already recorded some songs, but we are still in the process of collecting better songs from songwriters. We will release Rain's regular album this October".

Se7en is currently recording his new album and will release it in the first half of the year. He is recording songs written by songwriters from YG Entertainment, but he plans to continue the recording process until he is fully satisfied with the results.

BoA plans to release her new album on August 25, the date on which she released her first album 10 years ago. Her agency, SM Entertainment, said they have been discussing the style of the new album because BoA released records in Japan and the U.S. since she released her fifth album "Girls on Top" in 2005.

Music industry officials are expecting that the four solo singers could set a new music trend in the Korean pop music scene because girl groups and idol groups have been continuously gaining popularity early this year as well as last year. A representative of an entertainment agency said, "It has not been easy for solo singers to succeed in the Korean pop industry. I am wondering if the four solo singers will succeed or not. If they succeed in the Korean pop industry at this time, entertainment agencies will pay attention to experienced and capable singers more than they do now".

In addition, an official at a performance agency said, "We don't know about the music style of their new albums yet, but their music will provide the Korean pop music scene, which features electronic dance music, with diversity and change". He added, "We highly anticipate the new performances of Rain, BoA, and Se7en, who have performed on major stages in Asia. Furthermore, Eru, Sung Si-kyung, and Eric will leave the army from May to October, after Kangta was discharged from military last month. Their comebacks are also drawing people's attention". Eru and Sung's agency said, "They plan to make a comeback this year".
