The German language. hahahaha I'm dying. I've always thought it was a mean sounding language. In high school my dad couldn't understand why I wasn't taking German as my language, since we were had German in the background.
update: I tried with all my songs and yes I know it doesn't work with every song. I just think it works if you play the song on time or it works with some sort of upbeat song. But yea, it doesn't work perfectly like you would expect.
