ninti,

True. Good catch.

svferris,

Say you have ten playlists. Say the first song in your root playlist (all playlists) is from alternative rock. The chances of the next song being from alternative rock are 1 in 10 (assuming you have same-sized playlist). So the chances of no songs from the same playlist playing back to back is very small.

Perhaps a future version could have an option other than random that blends the different generes/artists evenly, kinda like a radio station. You won't hear the same artist back to back on the radio, unless they do it on purpose.

To all,

How can you measure perfect randomness? It could pick the same order 100 times in a row, yet still be random.
