You don't need to make it less random to achieve that. A 100% random shuffle won't have that issue, you just have to make sure it's actually a shuffle and not something else.

Given a set of songs or albums {a, b, c}

Suppose shuffling results in ordered set [b, a, c]

Suppose user plays through the entire set. Now it's shuffled again before repating.

Suppose the new shuffle results in ordered set [c, a, b]

The user now hears c play after c

[Dylan16807]

I'm going to ignore the other ways to handle that and just point out that that is multiple shuffles and won't be a problem if the user initiates all shuffles.

[xtagon]

If the user has to initiate all shuffles, it won't play continuously. If you handle it another way, that demonstrates that it doesn't "just" work with a pure shuffle without using those tricks.

1. Without a clearer spec, we should not assume the user wants any repeats at all.

2. Your claim is not even true as written.

3. I'm tempted to assume the user has a reasonable amount of music, so it will last as long as necessary. And you can't force me not to assume that.
