LOL!!! Why do the white people keep bringing French into this? (totally kidding). In my opinion, conversational Japanese sounds really annoying because it sounds like people are muttering in the front of their mouths. I also agree that Japanese women speaking in really high pitched voices are really annoying. However, Japanese culture is awesome. Cantonese sounds interesting lol. It definitely doesn't sound like Thai or Vietnamese which have really awkward sounds/noises. Thai and Vietnamese sound like whining..... Mandarin sounds nice when spoken quickly and softly. Korean is my favorite by far. The sounds just sound really cohesive, and pleasing to the ears.
