I discovered the fingers on my right hand barely brush the bottomed edge of it when I make certain multi-key keystrokes. Right where the play “button” was by default. Took me forever to figure out why Music was opening “randomly”.

I ended up setting the touchbar to static, not per-program customizable, and replacing most of it with a “spacer” element. Fixed the problem.

Luckily they’ve realized they were a bad idea and my newer ones don’t have a touchbar.
