I love both songs lol Sunrise is a nice, upbeat summer song, and Sunset is a beautiful, wonderful summer ballad. Music-wise, this is an amazing single, because both (well, probably all if you count the mashup) songs are really good, and since Ayu doesn't have too much of a competition for her first week, let's hope people realize it's a great single and that it sells well =D
