I found an Exploit for Ice Cream Beat:
Pause a few times quickly before the song starts when the numbers start appearing on the screen.
After the first Demonstration of the first part of the song when a ring is about to appear: Pause one more time and wait for a few seconds and then unpause.
Once you're unpaused - the frame rate might be slowed down and then it's easier to get the beats.
I asked a friend who has this game to try it out and it seems like it works but I don't know, it works on a regular PS4 but I'm not sure if it'll work on PS4 Pro.
