Very happy with the Favorites Mix after the first refresh. My first one last week was all hip hop, now this week it's all indie. I kinda like that they're changing up the genre each week so that the playlists have a flow to them. So far, both have been incredibly on point with my listening habits, in some cases going back several years in my play history to find stuff that was in heavy rotation for me a long time ago. Love it.
As for the new music mix? I don't think I've given Apple Music enough Love/Dislike feedback to make this one very good. I am now going through and either loving or disliking everything in the hopes that it will improve over time. Will be impressed if there's a major turnaround when it refreshes Friday.
Edited to add: after just one week of Liking/Disliking things in my library, the My New Music mix has improved DRASTICALLY. It's again, pretty indie heavy. But the first dozen songs in a row, I loved all of them instantly, and I had never heard of any of the artists before. Ended up adding over a dozen new albums to my library as a result of today's mix.
And all the music is legitimately new for the most part, with a lot of the records having just come out today. It would appear this is sort of a combination of Discover Weekly and Release Radar, but definitely leaning more towards newer music. It wasn't all stuff I loved, there were a few clunkers in there. And it was the 2nd week in a row I had to tell them "No thanks on this Lil' Yachty fella", but I just disliked and moved on.
I came away really impressed with both of these playlists after seeing them change week over week. This is exactly what I have been waiting for from Apple Music. Also, I know these are done by algorithm (they have to be, right?) but it really does flow like a playlist where the sequence and flow was considered by a human being. Job well done if this is all machine learning or whatever.
