@hi for music definitely symfonium, in combination with self-hosted subsonic it's awesome
for video i use VLC and photos just the stock gallery app, nothing fancy there
@hi
I've enjoyed having switched from #GooglePhotos to #ente recently - there's a couple of things to get used to, but overall I like it. My main goal with it is photo backup, and being able to search photos by content ("mum", or "pasta recipe").
For music and video I use #VLC (but #Voice for audiobooks, and #AntennaPod for podcasts).
