The only way that an individual can "discover" new music is by hunting and pecking for it.
Think of a record store circa 1980. If you blow past all the Styx and Sugar Hill Gang being marketed in the front windows you'd have to go through the entire A-Z alphabetical archive to find a 12" square piece of vinyl with a name that you've never heard of. Rack after rack, row after row, looking for something that looked interesting just based on its sleeve art. With Apple Music, same thing. The only way to discover something new is by using keywords and using the Search box. Start with "A", work your way to "Z" so you don't miss anything.
All other methods are curated by someone or some corporation, no different than Rolling Stone magazine reviews in 1980. Some editor in San Francisco deciding which albums are good or bad and, more germainely, deciding which ones were even worthy of reviewing to begin with. Today's Beats 1, For You, custom playlists, somewhere in Cupertino there is a guy who decides what makes the cut as a 'push' for the month of August and who gets ignored, someone is deciding the track list for the Apple Alternative Radio station.
"Discovery" is a myth. It's cumbersome and unrealistic. And it's the only thing justifying Apple Music as a value of any sort. Hence the issue.

This is the oddest argument I've ever heard. Did you used to do this? You'd go to a record store and start at A and ask to listen to every artist you hadn't heard of before?
If so, then my hat's off to you. You must have listened to an incredible amount of awful music to get those 25,000 songs you like.
However, if there's a service that takes what I like, based on my library and inputs I've given, and can offer me new tracks I've never heard that are in line with my tastes, that seems to be a much more fruitful method of discovery than manually going through every album I've never heard before. Now, you may say Pandora does that. I've found that on the whole, it does not. Because Pandora can't really know what I have and haven't heard. I can thumbs up or thumbs down to tell it what I do and don't like, but that's not the same as discovering new music.
In theory, Apple Music SHOULD be able to know what I have and what I don't have and recommend new things based on what I don't have.
That being said, it seems like AM hasn't really come through on this yet, so I can see why that aspect would be disappointing. But make no mistake, that is where all these services are trying to go. We may see the primary method of music consumption going from albums/singles to playlists. In which case, services like this will be tremendously useful, because a song might be great in the context of a playlist, but you don't feel the need to own it.
That being said, streaming services have one major advantage over radio stations. There's a limited amount of radio stations that cater to a specific demographic, and in terrestrial radio, those stations are hamstrung by corporate agreements on what to play when. So the likelihood of discovering new music on the radio is nil. iTunes Radio/Pandora is slightly better in this regard, but again they tend to track toward hits and recognizable songs, plus the aforementioned issue that they don't really know what you have and don't have. Streaming can offer me a limitless supply of suggestions, free of corporate tie-ins and narrow restrictions of genre. Now, Apple Music certainly has artists it's promoting, but if I never listen to Drake, I'm not going to see a Drake playlist show up in the "For You" section. If I listen to a lot of Queens of the Stone Age though, I may see a KYUSS playlist pop up, or a playlist of new stoner metal.
I do think streaming services can be used to aid much greater music discovery than we've ever had in the past. And as the technology gets more sophisticated, I think we'll see exactly that happening.
I realize that's not much value to someone who wants to listen to just the same songs over and over, but it's very valuable to lots of other people.
