The songs are in-your-face cheesy, but "My Only Love" serves as an incredible piece of nostalgia for when Anime in America only consisted of a couple shows, no one knew what Anime was, and Sailor Moon was the clear stand-out. I still get chills when that song comes on.
Sailor Moon is probably the only series where I liked a good portion of the dub songs that replaced the Japanese ones, not that I disliked the original songs. ^^
Jennifer Cihi has a really nice voice. ^_^
