It’s at least used in RTX Global Illumination as far as the nvidia site mentions it, and I heard rumors about Cyberpunk getting it, but unsure if it’s used in current tech or not. I think I heard mentions of it in some graphics review of a game.
Skimmed comments, but if you download and manage your music on your own on a machine you can have a super simple setup like I do. All music is synced using Syncthing to my phone. So my phone gets local storage, and then I use Poweramp (android) to play it.
I pretty much have a folder for all the music though. But I assume you can sort music into folders to have them as playlists. But perhaps not as practical as desired.
I use Taiga for tracking anime, and it can auto download torrents, my torrent client can auto add torrents downloaded by taiga. For airing stuff I don’t auto download things using taiga though, as it will usually take the first and best torrent it finds, so I opt to just check what’s foud and double click the matches when they are the right version.
