Shuffle play is NOT random.

[Ankosi]

This is getting very ridiculous. When I shuffle my playlist of say 70 songs, which all come from a total of 4 or 5 bands, I get a long block of all of one artists's songs being played, and then another block of another artist's songs being played, and so on.
I want a MIX. What is the point of having shuffle button if I don't get that???? I tried shuffling the playlist while look at the queue several times in a row, and it shuffles them, but still keeps all the songs of certain artists grouped together adjacently. I don't want to hear the same artists over and over when I shuffle! And it is not just this one playlist it's all. Why can't Spotify fix their algorithmic and do that? Apple did it! Tidal does it! SoundCloud does it!
I want a real fix and solution this time for IOS. Not for desktop or PC. I am very close to going to another music streaming service.
