Unfortunately Spotify is near useless to me now as it is inundated with kids songs polluting my lists, and the occasional listen to a song outside of the norm for me somehow also does the same thing.

They REALLY need a way to easily say "exclude this genre entirely from my recommendations" or from specific auto-lists. I'd also love a way to reset the learning features or specify more clearly "only learn from these playlists."

That echoes what a I've heard from a few others.

It just bugs me that an entity with such a forte in data mining can err that much, to the point where they're losing a losing customer to the competition.

The feature Spotify has where artists curate their own playlists is also amazing in my experience. (for new music discovery)

Indeed. Big fan of the Arcade Fire ones
