How might I verify my macOS Apple Music Library is not corrupt?

In macOS 27.01. and Apple Music 1.7.0.163, I am experiencing regular problems when drag-and-dropping tracks from Smart Playlists viewed as songs to other playlists--specifically, each track seems to be duplicated 3+ times on the destination playlist. This doesn't occur when using the contextual menu "Add To Playlist", only during drag-and-drop. I've reported this the only place I know how, at Apple Product Feedback.

I'd like to confirm that there isn't some corruption in my Apple Music Library. I've had it for a long long time, there's 90,000+ tracks there, etc. I've done restarts and Update Apple Library. Are there other things I can/should do to make sure my Apple Library is working properly, or to perform maintenance/cleaning on it? I am pretty confident that the issue I outlined in the prior paragraph is a bug, but would like to be 100% sure the issue isn't on my end, and I would be devastated if there was to be data loss associated with my Library.

Quickest way to rule your library out: quit Music, copy Home > Music > Music to another drive first, then hold Option while opening Music and choose Create Library. Add a handful of songs, make a smart playlist and drag from it to a normal playlist. If the 3x duplicates show up in a fresh empty library too, it's the Music 1.7 build and not your 90k library, and you Option-launch again to pick your real library back. For a health check on the big one, Katalog (musickatalog.com) runs alongside the Music app and lists missing files and duplicates in its sidebar.
