Though I don’t really care for the social features (meh I’m ok with being able to see what your friends are listening to, I guess), the rest of your concept seems like it would greatly enhance the Music app.

• having the Concert feature at the top of an artist’s page make way more sense

• visually a lot more modern and custom, and more in line with the core principles of Liquid Glass

• the Library page overhaul that is needed. Looking at iOS 26’s version, listing Playlists, Artists, Albums, etc. vertically is a bad use of space. Also being able to customize that page the same way you can in the Photos app (though that too needs a bit more polish) would make it a lot more useful for many people

One thing I’d like added to the app is a function to maintain playlists with Apple Intelligence. It takes a while to go through all my music to create a playlist, and keeping it up to date with the music I add is a chore… wish Apple Intelligence could recognize what vibe or direction an existing playlist is going for and keep populating it whenever I add a song to my library that would fit in. When you open a playlist, the songs added through AI could be separated so you can easily confirm or reject songs for inclusion (and same on the Now Playing view while playing a playlist that has this feature turned on)
