Pure randomness isn’t great for music playlists. The algo needs to account for recency so you don’t hear the same some 6 times in a row. Technically still random but no one wants that.
That’s the difference between randomizing a playlist and shuffle play. If you randomize a playlist, the songs will never repeat unless you have them in the list twice. YouTube Music’s shuffle play often plays the same twenty songs over and over out of a playlist with over six hundred songs.
