A lot of people ask me what the chances of licensing their music are.  It's hard a question to answer because there are so many variables involved.   There really is no one size fits all answer. For example, how good is the music being pitched? What style of music is being pitched?  Who is it being submitted to? How often is it being submitted? How often are you following up on your submissions and so on...  There isn't any single answer, because it really depends on a lot of factors.

I can understand why people ask questions like these, but it's a counter productive way to approach the situation.  It's much more effective to simply decide that licensing your music is a goal and then ask questions that will lead to success.  For example you can ask:  What kind of music is currently being licensed a lot?  What is the production quality necessary for music to be licensed and how can I get my music to meet those standards?  Who is looking for the kind of music I create?  What styles of music that I enjoy writing are actually in demand?  Asking these types of questions will point you in the right direction and ultimately lead to your success.

Worrying about how hard it is to license your music or what the chances of you succeeding will only serve to deter and delay  your progress.  It's an understandable thought process, but it's completely pointless.  Don't do it.  Instead focus your efforts in figuring out how to move in the direction of your goals.  Success is often times a matter of asking the right questions.
