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?
Already mentioned, but Strawberry is worth checking out. If Quod Libet works, stick with that. I liked it when I used it.
mpd has a number of frontends.
No longer developed I think, but I’ll mention gmusicbrowser as it used to be my go-to.
cmus is what I use now.
I also have a very large library and use Debian 12.5 so I’ll bookmark this thread for later.
