I got so fed up with the iOS Music app bugs and the software engineers' inability to fix them, I emailed Tim Cook directly: tcook@apple.com
I listed these bullet points in the email. If you have any others, add to the list and send to him.
iOS: Album missing artwork (even after removal of entire library and Music app, and re-sync via macOS Music app).
iOS: If an album is removed from iOS Music and is re-synced from macOS Music, iOS removes album artwork.
iOS: Audio cuts out before song is finished playing. Only solution is to delete and restore song or album via macOS Music app and re-sync to iPhone.
iOS: Song playback jumps to next song before a song is finished playing.
iOS: Wrong artwork is shown for an album.
macOS: Audio cuts out before song is finished playing, must re-download from iTunes Cloud.
macOS: Wrong artwork is shown for an album (different from wrong artwork in iOS).
macOS: Audio cuts out before song is finished playing, skips to next song. Only solution is to delete and restore song or album via macOS Music app and re-sync to iPhone.
macOS: “Year” release date of albums is missing.
macOS: Purchased albums from iTunes aren’t showing as Purchased when navigating to Artist > Album in iTunes Store. Can’ re-download. Can only re-Purchase.
macOS: Purchase date of many albums are missing.
macOS: In sidebar, clicking Artists link displays list of artists but the majority of thumbnail images are missing.
macOS: Removing all songs can be performed from iPhone Sync Settings when iPhone appears in sidebar/Finder. But songs aren’t actually deleted from the list. All remain.
I urge everyone reading this thread to submit a bug report as well. FWIW.
