Increase the quality of the music that can be found in a search
Goto the registry and then
HKEY_CURRENT_USER\software\Kazaa\advanced . Once you have selected this there should be a DWORD that says LimitBitrate (If there is not one then create a new DWORD called "LimitBitrate")
Once you have done that enter a value of 0 and you should be able to download those 360KBPS files. They are rare though but there are a few.
You can also change max search results..
The maximum is a 100 but you can also make it 10000 if you want
go to: HKEY_CURRENT_USER\software\Kazaa\advanced and change Dword MaxSearchResult to what ever you want.
