I have not used the gold.
But, I have used Kazaa. It is outstanding. For example, I now have a respectable collection of Jimmy Rodgers, Burl Ives, Sons of the Pioneers, Carter Family, etc. etc. etc.
Like Cluin, eventually I have found everything I was looking for including obscure things like "Dangerous Dan McGrew" by Guy Lombardo.
Sincerely,
