I know of many songs that are produced using the Vocaloids Hatsune Miku and Megurine Luka (both female). Magnet and Ladies First are two that I think of right now but I know alot more including those two I really like the ones I have heard. And I Kissed A Girl by Katie Perry but i do not really like that one, maybe it is the tune? Many songs by TATu. I liked those ones and often they made me cry like Magnet does. (sometimes Ladies First too but that song is so upbeat) (Did not cry during I Kissed A Girl because I did not hear in the lyrics anything to cry about as it was simply she kissed a random girl she did not know and she liked it. perhaps more meaning exists in the follow up or maybe there is space in the that must be looked into in order to see the true deep meaning. I am looking too far into this song) I will be sure to look at some of the other songs here.
