Give me some sliders to change parameters of my discover weekly playlist

[Jim1Ill]

My Discover Weekly playlist has frankly become unusable. 

I'm a dad, so I play pretty wide range of stuff, either for myself or for my daughter - but the Discover playlist is 100% full of songs that are on high rotation on classic rock stations. I get that that might be reflective of some of my activity, but I don't want that in my discover list. There is not a single artist in my Discover Playlist right now that I don't know, and not a single song of I haven't heard before. 

Did the algorithm change this year or something? As soon as a few months ago it was still mostly great with a few skips, now, thoroughly useless.

So, maybe we have some control over parameters in the algorithm? Newness, weirdness, distance... I dunno, something to boot some of this snoozers out of my playlist.
