think popcorn time for mp3s/flac instead of mp4.
a client can selectively list and then stream individual files from a huge torrent. if you've ever watched illegal movies/shows on those random domain websites, you're likely streaming it from a torrent on the backend somewhere.
it wouldn't surprise me if we start to see some docker images pop up in a few days to do exactly this as a sort of "quasi-self-hosted jellyfin". Where a person host a thin client on a machine that then fetches the data from the torrent, then allows the user to "select" their library. A user can just select "Top hits from the 80s" and it'll grab those files from the torrent, then stream or back them up.
I don't really see why it wouldn't, from an end user perspective, be any different than a self hosted jellyfin or plexamp.
