Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time. The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves.

I recently heard a news , YouTube set up a music library , the music in the library can be easily use , they all royalty-free music here , YouTube was very careful on to add advertising in video , because if these videos has infringing music in it ,once the video producers been implanted advertising revenue , then this video constitutes an offense . so , It is the good idea to make an music library by YouTube.

Each audience should have a genuine sense of respect to the copyright , I think , for some special audience –fans , they will really really really respect the copyright owner ,such as I alway like to buy the combination of my favorite albums , I never buy
Piracy one, it makes feel happy when I brought the record perhaps it is because of the power of the star.

Now, royalty-free music is still very scarce , I hope more and more artists and websites offer royalty-free music to us.
