There used to be an iTunes option to adjust the degree of "randomness" in shuffle mode, by setting a probability that the next song would be by the same artist as the previous one. But now I can't seem to find that in iTunes (8.2.1). Is it still there somewhere and I'm just missing it? The reason I'm wondering is that I was playing a playlist in shuffle mode and I got 3 or 4 songs in a row by the same artist before it switched to another artist. That's the first time I've ever seen that and I don't know what prompted it. Not that the effect was bad, but it was unexpected.
