Redacted.ch is the best music tracker and has an interview process that’s open to anyone (
https://interviewfor.red/en/index.html). The interview process is basically entirely copied from what.cd. Spectral analysis is the only part that actually requires any thought but you’re allowed to get a question or two wrong on the interview and I think you can retake it a couple times if you fail. For movies/tv the best ones require working your way up on Redacted by uploading stuff and having a high “buffer” (total uploaded - total downloaded). To find stuff to upload you can either buy CDs or just transcode existing FLAC releases into MP3s if they have not already been converted. You can circumvent grinding your way to higher level trackers by making friends on IRC who will invite you. Or just buy an account and hope you aren’t caught (not advised).
