floyd,

Thank you for your comment. I am glad to know you enjoyed both versions, especially you like the vocaloid version.

I used "Mew" as a vocaloid singer. I think her voice is very natural compared with others and also attractive to me though I have tested just a few of them. Probably many of them are made a little bit different from natural human voices intentionally, e.g. like animation characters, to emphasize their own personalities.
