Remake of songs, cover of songs!~

 
There are many of remake songs.
Nowadays, I recognized that many korean singers did a cover of j-pop.
Example : Hirai ken -  瞳をとじて
                Nakashima Mika -  Yukino Hana : 雪の華
                尾崎豊 - I LOVE YOU
                Wands -  世界中の誰よりきっと
                 X-Japn - Tears
                 Nakashima Mika - 桜色舞うころ 
                   Etc....
