Blanket License: Allow users to license production music with a broad range of usage.  Typically a license is restricted to a specific geographic area or DMA, such as a TV stations broadcast area or to a country, like the USA.  Blanket Licenses always come with a duration or time limit.  Most are between 1 and 3 years but Network licenses can be as long as 5 years.  A Blanket License can have restrictions on how many songs can be synchronized but typically they have unlimited usage within a set of defined Production Music Libraries.  The usage of music is always limited to specific type of production or a set of specific production types.  For Example: Broadcast, Web Video, Corporate Video or Commercial Productions to name a few.  Blanket Licenses can range in price anywhere from $500 on the low end to $100,000+ on the high end.
