Most of the discussion and sources of content talk about movies and series.
I’ve been recently looking for psy and techno music, finding FLAC or WAV with active seeders feels like striking gold. It’s definitely been a while since I’ve looked for active torrent sites and it feels more barren than ever.
It can download FLAC through deezer. There’s a HiFi plan that supports FLAC on deezer.
It’s probably not the absolute highest quality possible but it’s still better than normal 128kbps MP3. (it also supports 320kbps MP3).
