That is ACC, still alive and kicking. Here is a gui front end for it, you can get it from fdroid or GitHub https://github.com/MatteCarra/AccA
The some of the old music sites are still there. But I would avoid torrentgalaxy.to it has curated weekly albums of top playlists from Spotify, tiktok, etc that have all the new stuff updated every week, for your local playback displeasure. Only uncool people play locally stored music, all the cool kids stream. Do not go there.
Ahh now I get all the R34 jokes on reddit or/memes today
