Production music refers to the library of music that is produced and recorded by a composer/ music producer for use in a commercial entertainment. This music is generally a part of a stock library and is usually licensed, which can then be loaned out for use in film, radio or TV program. The stock music licensing allows the stock music library to be owned by copyright owners. The owners of all these tracks do not have to seek permission for using this music from the composers every time they wish to make use of it.
Licensing enables producers to retain the rights of music thus protecting the originality of the musical piece. It will also help them control the usage of music, ensuring that it is not used everywhere, thus associating the piece of music with a particular type of videos/ products. Using the same backing track for a variety of productions, especially if they are vastly different from each other can actually be counterproductive in the long run.
Thus, if you are looking for music licensing for film, but do not have the resources to have a custom music piece composed, you can opt to buy stock music instead. The vast variety of stock libraries will spoil you for choice, where you can pick the right kinds of sounds to suit your movie. Since most stock music is composed and stored in terms of genres, it will be easy to sample out and find the kind of music that fits your movie.
If you are a small/ independent movie producer, you are better off doing business with a smaller stock music provider. Most new talents start out under smaller stock music libraries, and you will have the privilege of working with new styles and sounds. It also works out economically, as they cost you only a fraction of what larger libraries charge. Smaller libraries are accommodating as well and can arrange for custom compositions based on your requirements. They are well equipped with professional grade studios and equipment to help produce top notch stock sounds exclusively for you.
So, regardless of the kind of music you wish to procure and use, in-depth research about all available options will allow you to get a closer look at all that are available on the racks. Once you are sure of the kind of music that you desire to have, just go ahead and indulge; you will get good value for your investments.
