[Bug] Replacing memoryBlock BRSTM causes board to lag.

[Sophilautia]

As identified by IncompetentHero, replacing the Round The Blocks music seems to cause the game to lag heavily when loading the minigame. It doesn't seem to matter what you replace it with.

This may also cause general board lag, still investigating that possibility.

For now I recommend removing the functionality to replace the Round the Blocks music from CSMM. @Deflaktor

I'm not able to reproduce this issue. I'd love to check with IncompetentHero to see if they see this same behavior in the latest version of CSMM.

(Also: the title says memoryBlock but the body of the issue says Round the Blocks, but I've replaced both with seemingly no issues, even on original hardware.)
