Its not that the playlist is not Random, but its in your mind

Dan Goding of Wired News wrote a beautiful article on media players that randomize. I have always run into the same problem where the playlist always seem to be predictable or not properly randomized. Songs by the same artist or from the same album often appear closer to each other than they should be. In some cases, an artist is even repeated twice or more when there is ample room for other artists in between.

Here are Dan's findings as he writes in his article: My IPod for a Random Playlist

The problem, it turns out, isn't that the programs aren't randomizing my playlists. They are. According to Jeff Lait, a mathematician and author of randomm3u, it's what's happening between my ears, specifically, in my expectations of what it means for something to be random.
