Random album radio has no biases, if you’re talking about the top level one on the home screen. It’s truly random. It sounds like you are looking for some thing which is less random in terms of spreading out albums by the same artist. It doesn’t have favorite albums, or bias for popularity.
There is also zero bias for live albums/tracks anywhere in the system.
There is bias on smart shuffle (if you have it enabled) and things like library radio and the style/decade radios which use the smart shuffle heuristics behind the scenes. There’s bias for popular tracks, highly rated tracks and less recently listened tracks.
Like you said, its a weekend, so a bit of patience is appreciated.
