How about a friend sent me a sample CD made up of tracks from lots of CDs in her collection ? Is that illegal ?

Or

How about the Listen Again feature on an Internet Radio site ? Is that illegal ?

By 'use of' - I meant any use by anyone that would be of an injurious nature to the author.

Singing the lyrics in the wrong key in a shrill voice would be injurious to everyone so would be covered. Therefore most people should be ok.

Now, what is the next charge I have to answer to ?
