Music library problem after Sonoma update

Hi Bill Spears,

Welcome to Apple Support Communities. To help locate your music files, we suggest for you to follow these steps as it may help:

Locate your Music files

1. In the Music app  on your Mac, click Songs in the sidebar.

2. Do one of the following:

* Find out where a file is stored: Select the item, then choose Song > Info.

* The path to the file is shown at the bottom of the File pane (next to location).

* Show the file in the Finder: Select the item, then choose File > Show in Finder.

* If you don’t see Show in Finder, the file may be in your music library and not on your computer.

If a song no longer appears in Music

If a song used to appear in Music but doesn’t now, it may be because the music library or song was moved from the Music folder. To make your songs appear in the Music window again, try the following in this order:

* Locate your Music folder in the Finder  on your Mac, then drag it to the Music window. Your songs appear in your library again. If the music library file is included, playlists, song ratings, and other information you created appear.

* If that doesn’t work, your songs may be elsewhere on your computer. In the Finder, choose File > Find, then search for a song by title or artist. Or search for “MP4” to find files downloaded from the iTunes Store or “MP3” to find songs encoded in MP3 format. Drag songs (or folders containing songs) to the Music window to add the songs to Music again.

Following these steps may help and is outlined in this article: Change where your music files are stored on Mac - Apple Support

If that doesn't help and you need additional assistance, we encourage for you to contact Apple Support through this link here: Get Support

Kind regards.

I, too, stored all my music on my devices, because I am often in remote locations without cloud access. After Sonoma update, I found my music in Home>Music<iTunes and followed your advice to drag and drop music files (folders) onto the Music window, which I did, and now, whew, a long time later, the music is still transferring, as you can see by the red dotted circles beside each title. Why did only that one song transfer and is playable? I will next consolidate the files according to the link included in your helpful response. What I notice on my iPhone is that any song that resides on the cloud (purchases by spouse on his iPhone)will not play in Music. Do I need to somehow consolidate the music database on our iPhone?s I would really his device, my device, my desktop to sync—is that possible? Could I have my library both on the cloud and on my device? My device would not update its stored library though, correct?
