OPTION 1: Each composition is in only ONE library (exclusive or not).
OPTION 1 RATIONALE:
If my works are in multiple libraries, they may compete against one another thereby lowering the price I receive. If each composition is in a single location, this is avoided.
OPTION 2: All of my pieces are in multiple libraries (non-exclusive).
OPTION 2 RATIONALE:
The chance of your compositions being heard is greater.
Any thoughts on the subject?
