Update all 6 released /pop YouTube descriptions to surface streaming links above the hashtags (🎧 Spotify · / Apple Music ·). Push live via yt.mjs update-meta. Backfill RELEASES.md with canonical Spotify + Apple URLs for every single; resolve hellsine's "Spotify URL pending" (now live: 1yauGyuJPMzDadtu8S5llk) and add amaythingra's Spotify Listen line. trancepenta is Spotify-only — not yet on the artist's Apple catalog. New file: pop/big-pictures/amaythingra.youtube.txt (had none). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
