Copyright Free

In our sound task, our group had to go on certain website called 'Creative Commons' to choose a suitable background sound/tune that would go appropriately with the opening of a film called 'Submarine'.
 The reason we were instructed to use those two specific websites was because they only consist of copyright free tracks.

  What is Copyright?
Copyright allows the music artist or the creator of other media's such as books, photos, film, etc. to rightfully have their work protected from being used without permission and being paid. They have legal rights to decide how their work will be distributed and the payments they will receive.
 If anyone does decide to not use copyright, this action is actually breaking the law!
