From Reddit:

What does everyone do to find new good music on AM? I’ve been having to use Spotifys discover and recommendations to get good music.

I prefer Apple Music to Spotify interface and usability wise but I really wish they would just up their algorithm game for discovering new songs or getting good songs based off “stations” I create based off a song I’m listening to. I sometimes get songs I already have or very mainstream options like Justin Biebers “No Brainer” come up and it’s like wow Apple lol

Here’s one response:

You need to put in a LOT of work to get Apple Music to work for you.

What Apple Music would like is that you select the genres and artists that you like when you set your account, listen to the stuff from your library or tracks suggested by For You and have Music do the rest. This works well if you only listen to mainstream stuff but falters if you look for artists with smaller listener counts (i.e. most of my library).

To fix this, you have to “Love” and “Dislike” a lot of songs yourself. For example, Music kept recommending Hip Hop for me (it’s probably the most popular genre on the platform); I had to dislike every Hip Hop song it threw my way for it to stop doing that. I also like Midwest Emo Pop Punk; most artists in that category are relatively unknown, so I had to import my Discover Weekly playlists for a few weeks and upvote songs from that to train Music to find artists like this for me. Apple Music’s For You didn’t get “good” until I spent roughly two weeks doing this. My New Music Mix is almost on par with Spotify’s Discover Weekly now, and I’m even getting Artist Spotlights from artists I didn’t think they did Spotlights on (like The Descendants).

The only issue I’m having now is that I’m scared to listen to hip hop on Music since I feel like it will begin recommending all sorts of Trap if I listen to even one or two songs (which I do sometimes; I like to stay current on the genre even though I don’t like it much).

I agree with all of the above, but I have found one path to music discovery that works well for me.

Recently, Apple Music introduced the Friends Mix to the top of the For You page. When I first fired up the Friends Mix, it was a bland rehash of my favorites. It was fine, but there was nothing really new to discover.

The key was adding new friends. Once I started sharing my Apple Music name (I embedded it in a tweet, which I pinned) and started following everyone who followed me, my friends list grew and my Friends Mix started getting interesting, much more enjoyable.

SIDE NOTE: My Apple Music name is ZZDAVE and I make every effort to follow all followers. Follow me and help me grow my Friends Mix.

As to liking and disliking songs, one tip is to let Siri do all the heavy lifting. Hear a song you like? Fire up Siri and say “I love this”. Siri will tap that heart for you. Same for “I dislike this”.
