I guess a practical solution is to be selective in what you select for the playlist creator. For example the top priority for me is the stadium and broadcast sounds. After I get all those in I include all the position player walk ups. Then I turn to the relievers (the team audio takes care of 3 universal songs for relievers which could lead to more space). If any space is left I add starting pitcher walkups. Also, when you play with the files enough you may realize where you can "use somebody else's name or stadium song" because it's a duplicate and possibly delete a file and pick up another playlist creator slot. It's annoying to have to go through this and I really expected the PS4 to have the ability to add more than the 500 songs. Then again the 500 songs is more than I had the last few years so I guess I won't complain.
