"in order to enhance the overall viewing experience of the movies they upload to the site. Amazon Studios also recognizes that it’s hard for filmmakers to get valid licenses to soundtrack music for their test movies. Sound and music are important parts of how test movies garner more engaged feedback from movie fans than just scripts alone. Every month, Amazon Studios offers a $100,000 award to the best test movie."
Of the selection, says Amazon Studios explains:
· The music will be grouped into 28 packs of related music, with 40-100 tracks per pack:
· The packs will be broken out into groups including:
o Movie genres likes comedy and horror
o Emotional categories like anger and joy
o Music genres from jazz to hip-hop and rock to classical.
· The music library will present these various packs for download; there will be an agreement step describing the acceptable licensed use of the music in the library.
