Very, very, very strange. I'm not too educated on the Hatsune Miku craze but I don't find the 'voice' to sound appealing at all. The technology is interesting, but if it's trying to sound exactly like a human's, it still has a way to go - especially with those extremely high pitches.

I like electronic music, and by extension how music in general can be affected by computer goodness, but I don't think this is all too effective.
