4. Some people believe that traditional music or folk music should not be protected under "private law" as the objectives of a folk artist is somehow different to "commercial artists", and that it should therefore be protected under laws that can protect its roots and heritage.

I think this last question is not worded very well, but it gets at one of the major problems that some people have with copyright laws. The current laws protect individuals, and work that can be proven to be the product of an individual composer, but there are no laws to protect the specific musical traditions of groups or communities. For example, should the Georgia Sea Island singers, or the Menhaden Fishermen, or the Old Regular Baptists be able to copyright their unique repertoire and arrangements, or does the fact that they perform "traditional" or "folk" music make them uncopyrightable? If the latter, what's to stop some Paul Simon wannabe from coming in and mimicking their sound, taking one of their songs and changing around some lyrics, and copyrighting the song as his or her own intellectual property. Current laws would favor the individual over the group. I know that this is something that's happened over and over again in the history of the "folk revival," but maybe there's a better way of doing things, that would allow unique cultural or subcultural sounds to be copyright protected.
