For the first time, I heard some Hatsune Miku songs today, on account of my Pandora station playing some. But I was surprised; her singing is actually pretty bad, because the syllables don't transition into each other--it's choppy and sounds silly unless she sings slowly. Also the voice tone is tinny, not very pleasant. Now I'm puzzled about why she's so popular. ...Unless I just heard some crappy ones...?
