Wow...I feel cheated! Why is that I have never heard the sounds of "cheering" or "whistling tunes" or the "slurping" sound when the villagers are drinking?

This is something new to me. I play V V 1, and 2 all the time, and have yet to hear the above mentioned sounds. The "cheering" sound would be a great addition to when they are celebrating accomplishments.

Any reason why?
