WebDec 3, 2024 · The common complaint is Spotify’s shuffle mode doesn’t feel random, but true random is not what we actually want. Flipping a quarter is a good example of this. If the coin is flipped 10 times, we expect to see a relatively even distribution of heads and tails. However, true random can just as easily result in 10 straight heads. WebAnswer (1 of 4): As James mentioned, the algorithm is optimal in most ways I can think of.

If a computer has access to purely random numbers, it is capable of generating a "perfect shuffle", a random permutation of the cards; beware that this terminology (an algorithm that perfectly randomizes the deck) differs from "a perfectly executed single shuffle", notably a perfectly interleaving faro shuffle.
