Strongly disagree. It’s probably a generational thing but I listen to music in albums, not in popular hits. This was by far the main reason I used to use Rdio instead of Spotify.
"My New Music Mix" is updated 1x week for some inexplicable reason (I know Spotify does this too), while it seems to recommend albums programmatically based on likes/listening habits. Other playlists seem to be manually curated and recommended based on genre.
Understandably, there is just no way to expect manually curated playlists to cover everyone's personal tastes.
I believe it is possible to recommend songs/artists/albums without favoring one form of discoverability over the other as it is currently done.
EDIT: Discovery is terrible, the only sites that had excellent discovery was last.fm (butchered by CBS) and what.cd (nuked by law enforcement)
As for the UI, I loved the Google Music one... when I was on Android. Now that I'm on iOS it's totally alien and just unusable because zero iOS conventions are respected, like I'm in a virtual machine, it's just frustrating. I find all of the other music platform UIs quite awkward and despite its flaws Apple Music is still the best for me.
Seems like we hit a wall and "all MUAs suck" just changed the M from "Mail" to "Music".
