We made a music system for the office I worked at a few years back; all of these options came up as possible meanings of "random". We ended up with a system where people could vote on which random they wanted, and all of them got used over the course of a few months. 3 and 4 were very popular.

It also sparked a lively debate about whether people actually wanted what they said they wanted or were just being difficult.

People are weird and English is imprecise.
