You can definitely make a truly random shuffle that doesn’t play the same song twice within a gap of ten songs.
You just make a list of all the song IDs that aren’t in the last ten played, and grab an item at a random index.
Randomness is a texture not a shape. Dice are random despite only being able to present six outcomes.
But then it is not truly random, that is the point.
The same song 10 times in a row also has a chance of happening in a truly random list.
Random pick without replacement is no less random than random pick with replacement. You just have a continuously smaller pool to pick from.
It's absolutely possible to have better randomness/shuffle without repeating songs so often.
there exist other random distributions than the uniform distribution
You’re thinking of a random sequence. We’re talking about shuffling according to a random seed.
