It doesn't seem very random to me. What user "vodka" said might be true. Whatever, I can deal with that. What really grinds my gears is that Spotify frequenty turns on shuffle when I want it off, and it frequently switches to "smart shuffle" when I want regular shuffle. "Smart shuffle" will mix in songs that it thinks you might want to hear. I can't tell you how many times I've turned off shuffle without having turned it on. I assume they have some competent people working at Spotify so I can't imagine how they could have let it get to this state.
