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.
Edit: Thank you all for all that valuable information. The reddit group really wasn't this helpful and valued making fun over adding real use able knowledge.
I guess it depends on how you listen music, most of the time it's nice to be able to torrent the full discography of a specific artist. Or just download an album you bought because you don't have time to rip it yourself (vinyls for example).
Some stuff is too obscure to be on Youtube, and IIRC the bitrate there is only 192kbps. It's acceptable as far as I care, but I would still look for better rips if available.
I stream music off of YouTube a bit and I can tell you the poor quality is notable on good speakers for certain artists/songs. It is jaring enough at times it breaks my focus and I switch to my local collection.
