[thelist] using music in a sales presentation

Now, IANAL, but -- if you take any of the classical pieces of music and 
then remix them, you should not be violating any copyright rules, since 
those works are in the public domain.  Atleast that's my understanding.

Not all classical works are in the public domain, but you can Google for
music in the public domain. You'll be surprised at what is available.
