10% doesn't meet the standard they taught us in broadcasting school... it
was so many measures of a work.

I know you cannot broadcast any portion of a cd that is in violation
of copyrright, and the copyright details must be printed on the CD or
accompanying documentation.  Logs are to be kept of all performances
broadcast, but of course no one every checks them unless there is an
official complaint in writing.

The details of copywrite law that apply to music and broadcast are huge
in volume, and take a lawyer to read.  I think it is impossible for any
individual, other than an attorney, to sort through it all, let alone
have a compliance officer deal with what is in print.
