I’m self-hosting my music collection (synology NAS), and while I’ve liked Poweramp, it only reads local music files, which means I have to copy many GB of music to my phone, even if I’m not particularly listening to it.

The Synology DS Audio app actually does what I want: it caches music locally as you’re streaming it, but it reads directly from the NAS.

The only problem with DS Audio is that it sucks as an actual music player.

Are there any Android music players, preferably FOSS or at least privacy-friendly, that will read from the NAS and cache in an intelligent way but also works well as an actual music player?

I did try Symfonium, but couldn’t get it to work with Webdav or SMB, plus the dev comes off as a real asshole, so I’d rather not give them money.
