body: I have two questions concerning copyright. 
  
  
  I need sometimes, to go to a website and listen to some sound samples to make a decision. If I then specify in a document the items in a contract, based on what i am listening to those samples, am I infringing?
  
  
  On one of the pages it says that it is prohibited to use the website for "any for profit uses".

  How is non-commercial use usually decided on, and how can someone test to make sure what they are doing will avoid copyright infringement?
