Music library manager recommendation

Hey folks!

I have a music library that has grown over time that I stream using navidrome. The issue is, some of the files have little to no metadata, I have duplicates of the same album, some artist names are misspelled, etc. An it is large enough that doing this completely manually would take a while.

I'm assuming (hoping) that I am not alone in this.

Does anyone have a recommendation of a tool (either standalone or part of a self-hostable media app) to basically assist in cleaning this up? It doesn't need to automate a lot of the process, but, for instance, querying metadata from an online source based on the file name / artist name, detecting misspelled artist names would already be interesting. Similar to Calibre's "retrieve metadata" for ebooks.
