First off make sure you have Kazaa Lite not regular Kazaa. Regular Kazaa is loaded with spyware and spyware equals spam. Spyware is a tool that allows ads to see where you surfed which results to spam e-mail. Now for the rest of you questions. I look for users that have Dsl or cable, also look at the users ping the lower the number the closer the user is to you. Finally look at bitrate look for MP3 files at a bitrate of 192 or higher it means it's a better quality recording.
