This (old) post details how to interfere with randomness to make it feel more random to the end user.
This reminded me of how many games “cheat” in a similar way to make critical hits seem more fair (increase the probability when it has not triggered for too long and decrease it when it just triggered)
For me it looped though the same 30 songs out of more than 1000. I much prefer a one time shuffle that guarantee all songs in my playlist, just in a new order. It’s not exactly rocket science, if it’s in the playlist it naturally should be played. That and horrible sync with local music made me just go all “offline” with PowerAmp on mobile and Foobar2000 on pc…
