anytime kazaa.  If u planing on editing or whatever for the game, I suggest using Adobe Auditions 3.0.  Very nice program.  U can do all sorts of neat things with it.  U can even fix distorted sounds and clean them up quite easily.
BTW, I will be releasing a new version of Sketchworks sound pack shortly.  Probably in a week or so.  I currently fixing some sounds in it that are at the wrong bit rate and khz range.
