If you’re familiar with What.CD and its shutdown, the power users and their local copy of that music archive moved over to redacted.ch (stats) and orpheus.network (stats). They’re private torrent trackers so they’re invite-only, but TMK they both still offer interviewing as an entry option: RED, OPS. The interviews mostly consist of technical audio information and private tracker rules. The main downside is that these trackers expect you to seed an equal amount back, so you don’t get a free pass to download everything without limits. Of the two, Orpheus is a lot easier to maintain “ratio” on since it gives you incremental credit just for having a large seedbase (even if no one is downloading from you). Ideally you should be on both if you’re serious about music collecting, but these days they are largely just mirrors of each other.
If you don’t want to get dirty in the private tracker world, I’d recommend Soulseek and RuTracker.
