The RIAA - noted for its exceedingly fierce stance on music copyrights - owns the musicunited.org web site.
The pages have now been removed but that watchdog of Internet freedom - our old pal Mr Google - has a copy of the some of the content of the removed pages cached on its site.
The original material can be found here.
And the cached Google musicunited.org pages are here.
As its own web site says: "The rules are very simple. Unless you own the copyright, it's not yours to distribute." Oops! µ
