Orpheus and redacted (previously passtheheadphones) both appeared shortly after what.cd’s demise. I believe they both now have more total torrents than what.cd, however the depth is still not what what’s was 9 years on (I know this because some of my uploads from what are still missing, partially because I no longer have the source material). And, the “cultivation” (ensuring no duplicates, recommendations for releases, general community, etc) is nowhere near what’s.

I would say all other media (or at least, the media I care about - film, tv, books) has what.cd equivalents, sometimes multiple. I think Spotify and AM killed 95%+ of “true” private tracker interest for music, especially with lossless and surround releases being available. The diehard core are still there (names from 15 years ago are still active) but it’s really not the same.
