how to clean up iTunes' folders of songs accidentally "removed" (vs. deleted)

Summary: trying to locate, select and remove all unlinked songs hiding throughout iTunes' artist folders. I am not trying to relink or recover missing songs and unfortunately Googling for a solution only yields those inquiries from others. Hence my post today.

Details: I often delete batches of tracks from my 10,000 or so song library. Songs I intend to remove from my library I always want to entirely purge from my drive as a space saving measure. Sometimes though I hit "remove" instead of "delete" by accident, and this action is undoable. This results in all of the tracks I "removed" being pulled out of iTunes while remaining in their individual albums folders among the hundreds I have for iTunes. Basically if I screw up and hit "remove," those songs are lost to the ether.

I wouldn't even have known of what I call the "ghost tracks" since they're no longer in iTunes, however I now use a Sonos system that pulls the tracks directly from the folders, so now the duplicates and tracks I intentionally deleted long ago are now playing again.

So I'm wondering if there's an easy way to separate out these songs I intended to delete. For instance when this happens in Lightroom with photos, I can pull all the linked files to another folder, purge the unwanted/unlinked photos, then move the linked pics back. Voila! Does iTunes have a similar capability possibly? I.e. move the linked songs to another location, purging out anything that's left, then moving songs back? I would experiment but I don't want to mess anything up I might regret. I prize my play count and other related data tied to my iTunes library and don't want to poke the beast for no reason.

Any advice/input appreciated. Thanks,

Max
