>A piece of software that plays (at least) one sound on every user action, and the sounds are completely arbitrary and 8bit at best.

I've worked places that have SAP, Oracle, and one place that had both. I've never personally used SAP, and rarely dealt with Oracle.

I would be curious though, if it makes that many sounds - how much error checking is done because something "didn't sound right"? Does doing business tasks sort of turn into a song, with an expected sequence of sounds which feels wrong when not executed correctly?

If I'm typing and talking to someone at the same time, I intuitively know "I typed f rather than g, quick backspace and keep going". Do people internalize the pattern of noises they should hear while completing their work?
