If pursuing licensing is your main focus, you need to plan this out long before you write your first song, let alone record it. The fact of the matter is, not every song or every genre works for licensing.
If your chorus is all about Sarah, but the main character of the show is named Amy, they aren’t going to use your song, no matter how perfect it may be musically. And because TV moves so quickly, they aren’t going to ask you to go replace “Sarah” with “Amy.” It either works or it doesn’t. For the most part.
