As a Seiko Matsuda（松田聖子）ballad, it's awwwwwwwwwwwwww-esome!
Perhaps I put in a few too many 'W's than needed but I just wanted to let everyone know how adorable this album-ender called "Sleeping Beauty" is. I believe it's on one of the Seiko BEST compilations I have but originally it came from her 9th original album "Tinker Bell" which came out in June 1984.
And if it strikes you that those two titles seem to have a connection, then you are quite correct. The album had its songs titled with various fairy tales in mind such as "Peter Pan", "Cinderella" and "Sleeping Beauty". Of course, that last track pretty much had Seiko giving the slo-mo play-by-play of the prince providing some mouth-to-mouth resuscitation to the young lady who was out like a light.
Written by Takashi Matsumoto（松本隆）and composed by Masaaki Ohmura（大村雅朗）, "Sleeping Beauty" has that potpourri of aidoru-ness with some contemporary balladry reminiscent of Yuming and/or David Foster. I mean, it's so adorable and gushy that it could also be mistaken for a Xmas song.
As for "Tinker Bell", it hit No. 1 on Oricon.
