Design Your Shuffle

An interactive exhibit — Random the Book

Repeat Tolerance 0%

How likely the same artist can appear back-to-back. At 0%, never. At 100%, pure chance — just like Spotify's original algorithm.

Artist Spread 50%

How evenly artists are distributed across the playlist. High spread forces balance. Low spread lets some artists dominate.

Recency Bias 0%

How much recently played tracks are avoided. At 0%, a song you just heard could come up again immediately.
