Japan's TV soap opera

 There are a lot of songs which became famous because of Japan's TV soap operas. Today, I introduce some of them. First is "Love so sweet". "Love so seet" is theme song of "Boys Over Flowers 2" ,in Jpanese "hana yori dango 2",which is one of the most popular Japan's TV soaps. "Boys Over Flowers 2" was broadcasted in 2007. Many people ,especially around teen age, watched the program so "Love so sweet" became famous. Accutually, "Love so sweet" got No.1 in 2007,3 weeklly song's ranking. The other reason why "Love so sweet" became famous is it is sang by ARASHI. They are one of most popular singer groups.
 Secound is "Everything" ,which is sang by MISIA. It was theme song of "YAMATONADESHIKO". "YAMATONADESHIKO" is the second highest TV program of an audience rating in history. Of course I also watched it so I listen to the song many many times. I think that nobody in Japan has heard this song.
