I have pretty diverse music taste, and Spotify's discover weekly is nearly universally bad for me. My wife's taste is less broad, and hers is much better.
I listen to a wide range of music and Spotify's recommendations had been really good for me. But more recently they have gotten terrible. It's really annoying and has made the service much less useful.
I recently switched to Tidal, and decent recommendations are what I miss the most. While I prefer getting music recommendations from an actual person with similar taste, Spotify was generally good enough.
That's more than can be said for Tidal. My recommendation playlists generally contain tracks and artists I already listen to (sometimes from completely unrelated genres), sprinkled with what seems to be random tracks from the "more like this" section of said artists.
Still not enough to compensate for the shit stream quality and ever increasing price of Spotify though...
My range is pretty broad as well, and over all I'm extremely happy with Discover Weekly. It's probably my primary vehicle for finding new music today, honestly. But it does seem to be pretty hit or miss for other people, for some reason.
