The Rose
The Bette Middler version comes to mind, although I know others have sung this song too. (Actually my daughter sang it and accompanied herself on guitar at a concert when she was about 11. That's a long time ago.)
You have met all requirements of this challenge as lyrics, soft focus and high-key are all present. Also you have nice colour harmonies in your arrangement.
Haven't heard that song in a long time. Love that song. Not loving this picture so much. The blur here just makes the image feel - blurry. Blurry with no purpose is just blurry. Doesn't do much to make the flowers interesting.
