Recover Missing Music Media Files

I know lots of people say this, but I have no idea why all the files in Music are missing.

I do have to say I did empty the trash for the first time in well over a year, about 800 Gb. I have not even looked at a music file since I converted my iTunes Library to Music, along time ago.

So I can't come up with any reason why my media files would be in the trash.

I thought the easy fix would be to restore my ~/Music Folder, the whole folder via Time Machine but, the media files are still missing. In TM, I used a backup about a month old and I've used music recently and it worked fine, so a month should be good.

Any help as to how to recover media files in Music, via Time Machine would be appreciated.

Or, if my music files are not in the ~/Music Folder, and not deleted, where would they be.
