iTunes shared library but it's more of a Mac OS problem really

[sbgirl54]

Hi there!
I wanted to share my iTunes library with my sister so I moved the iTunes -> music folder to the 'Shared' folder, I redefined acces paths and all but now... all the 334 subfolders of my library are 'read only'. so I tried to chmod -R a+w //path// but it didn't work (operation not permitted) and I don't have an idea of why?? 
other ideas?

Ok well i dont believe it is a Mac OS problem. if you re-directed the folder to the shared folder you may have skipped a step before doing so. when you purchase a new song from iTunes does it automatically go to the shared?
