Algorithms for randomness on things like spotify cant actually be true random because true random will sometimes do weird shit that makes users think its broken. Like if you put 10 songs from 10 artists on a 100 song playlist and hit random there is a not 0% chance that it will put all 10 songs from 1 artist in a row.
I used to be a street racer type jackass 20 years ago and I was religious about this. Never kept so much as a paperclip in the car. When I was heading out to be a dickhead.
I know 3 people who the police charged with “Possession of burglary tools” for having mechanics gloves and basic tools in the car because they didnt actually catch us racing so couldnt do anything.
