Shaken Not Stirred is for shuffling large playlists that have multiple entries of songs you want to hear more often than others.
Beyond just shuffling a playlists songs in a random order, it adds jukebox style options for managing the separation between repetitions of the same song: evenly distributed with some random variation, or just enforce a minimum separation. With even distribution, a song that is in the playlist say 4 times, would play at one random place in each quarter of the shuffled playlist.
The idea is like listening to a good radio station: the next song could be any one of a few hundred different songs, and your favorite songs get played often, while there are other songs that you like to hear only occasionally.
With other programs ordinary shuffle on a playlist that has repetitions of some songs, those songs would of course play more often. Unfortunately, normal random variation would sometimes put most or all the occurrences of a repeated song close together, even playing the same song twice in a row, with other long stretches of the playlist where you never hear the song. Shaken Not Stirred was written to solve that problem.
