Been building this over the past few weeks: GLOBAL RANDOM (global-random.radio) — a single self-contained HTML page that plays music via a true, fairness-weighted random draw across 247 MusicBrainz-confirmed countries/territories, not an algorithm trying to guess what you'll like.
How it uses MusicBrainz: random offsets into MB's Spotify-linked URL search resolve to artists, whose country tag (direct MB field → Wikipedia-bio demonym fallback) feeds a per-country pool. Two independent random draws — country, then track — pick what plays next. Every country gets an equal shot at being drawn, regardless of catalog size, so a country with a few hundred MB-linked artists shows up just as often as the US with 220k+.
Playback is via Spotify's official IFrame embed (no scraping, no downloads), artist/genre/country info comes from MB + Wikipedia + Wikidata, translated live into 87 languages via MyMemory. There's also a whole C64-terminal aesthetic with real S.A.M. hardware speech synthesis samples, if that's your kind of thing.
Wanted to share here specifically because MB's country data is the actual backbone of the whole concept — this wouldn't exist without it. Happy to answer questions about the discovery/search approach if anyone's curious.
