Thursday is code puzzler day here at DZone. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable.
Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer. It's all about the participation!

A Reliable Playlist Shuffle Algorithm
One thing I hate is when an implementation of shuffle on a media player results in a song repeating sooner than I would like, or earlier than it should. The challenge today is to write a method that takes a list of Song objects (with title, album and artist fields) and ensures that the space between a song repeating is as much as possible without having the same pattern used if the shuffle goes into a second (or third) run.
