When I go on vacation I prefer to keep my smartphone with WiFi and mobile data off, but I really don’t like the way Spotify handle offline content. Most of the time it doesn’t download everything and when I do a research, it show me even content that’s not available offline (how can it do that?). Is there a selfhosted service that I can use to download my playlists and play them with an Android app that can download them?
Lidarr to download music, has Spotify playlist integration, only problem is it pulls by alblum not by song.
LMS to play music, it supports selecting tags to use.
Picard to tag the music. Kinda optional, but using plugins it can pull genre, moods, and BPM, which I liked using to make a smart playlist to get songs I like the sound of without 100% hand picking out of thousands.
I personally use lidarr to download and picard to tag, but use plex/plexamp to listen locally and on my phone
