Not sure, I assume metadata like the song used and level length played a role

In reality it usually just found a bunch of unrelated stuff for old levels and for newer levels it just gave you the level itself and a bunch of its copies

It gave you levels the server thought were similar to the one you were playing - I always imagined it a bit like the equivalent of the "recommended" section you see next to YouTube videos

It was for some people in the past but in my case it looks like I have to click the button

my controversial opinion for the day is that I'm actually somewhat of a fan of dubs, but they have to be human created...
