That's an interesting view into the inner workings of my favourite music player. However, as a lot of people also comment on the article:

The main problem with Spotify shuffle is that it plays the same songs over and over while others remain unheard forever. (Even today and this article is from 2014, as another commenter pointed out)

I've wondered this since the days of Rdio(RIP) — is it possible that music services are weighting the probability of songs based on cost-to-them to play?

I play Spotify all day from my library (~10k songs) and it _seems_ like it will always choose a live version of a song (if available) over the album version and it will consistently play 1 specific song from an album every single time (seemingly ignoring the other 10). There's this one Elliott Smith song that will play every_single_time, despite having 5 albums in the library.

Totally agree with the article's comments about perceptions vs realities of "randomness", but it seems that there could be other "business" weightings at work.
