I am running RCT3 Platinum on a MacBook. I am running into an unusual problem. When I play music on loudspeakers in my park it doesn't loop. Once the music track ends it doesn't loop and play again. Any ideas why? How do I fix it?

I have the same problem too, glad I'm not the only one.  I looked through the music folder many times and I saw nothing wrong.  Whenever I would play a song it would just end like you said.  I was wondering If you found out how to fix it yet.
