Selfhosted

Not OP, I've kinda had a middle of the road experience with it.

I run JF and Plex on the same shares.

I dropped 10k tracks on it and a bunch of audiobooks, my stuff is 100% tagged.

I use tailscale to get to the server because here's no Nat Holepunching going on.

I try to use it as much possible for audio, but some days, I just give in and use plexamp (like a guilty pleasure)

cons:

• It has issues with displaying some of the songs, they're tagged right but you just can't find some of it. They're all Discogs coded, so there's not even a lot of extra characters.
• It doesn't always remember where in a book I am,
• It has no idea about collections of book files.
• Search is very slow, (yes there is a plugin for this, yes it's complicated enough I haven't tried it yet)
• Scrolling a large list is stupid low, it should just stream everything text into ram and bring thumbs in on demand
• Finamp: Finamp is barely a wrapper for the JF engine to the point that they can't implement effects or crossfade without the feature being added in JF first. But JF is just using a ready-to-go library to play music, so changes to JF require upstream library updates. Audio development feels stagnant.
• Finamp scrolling loads one letter at a time. Scroll to Z? you get to wait, A....B...C...D...E...F...G...H...I...J...K...L...M...N...O...P...Q...R...T...U...V...W...X...Y...Z, no skipsies. It literally takes me a couple of minutes to go to songs that start with Z.
• Plugin installs are complicated and poorly documented, and compatibility with versions is dicey
• Finamp: If you lose the network in the middle of a song, you can soft-lock the app.
• Finamp: occasionally crashes if left for a long play session on my late-model Android phone.
• No options to cast.
• No listening through a NAT without port forwarding (which is dicey without a security team)
• No 2FA
• Finamp?: Shuffle is too random, you can get the same song to play twice in a couple of minutes. it needs to pull at least a couple of hours of list and shuffle that, rather than random play.

pros:

• It's free
• It works good enough-ish for a daily car ride.
• It has some form of limited home-grown fail2ban
• The developers are super nice people.
• I exported my Plex playlists and used some Python to turn them into m3u lists, which worked fine. (Would be a cool feature to import from Plex)
• Playlist and Shuffle work mostly fine.

Can this edit the metadata in bulk? I'll have to give it another shot. I'm pretty sure the album artist was the the problem, and I couldnt just delete that bit.
