back when I used xubuntu I used gmusicbrowser.
Now, debian 12.5 netinst came with quod libet installed and it can handle 60k files so far.
note that my music collection is stored in 4 different SSD.
If there is anything better than quod libet, what would it be?
Strawberry or Clementine. I mean 100K entries in a database is nothing. Even for SQLite. You can add multiple library locations, this is no problem.
You probably want Strawberry as it is newer and maintained, but I still like Clementine for the extra features that Strawberry doesn’t have yet. For you probably, not a big deal - things like podcast support, cloud support etc.
