The app reads the playlists as before and hands the missing tracks to
MusicWorker.kt, which runs every 6 hours and once whenever the list
changes, on unmetered networks with the battery and storage not low.
MusicFetcher.kt downloads each with the token from JellyfinTokens, works
out its tempo and appends a line to fetched.txt, which the app takes in
as it opens and as each track comes. The app's own download is gone.
