Reading Discogs have and want counts.
Age and price on their own don't tell you much about rarity. The best public signal is the community data Discogs keeps for every release: Have — how many Discogs users own it — and Want — how many have it on their wantlist.
VinylRank turns those two numbers into a simple tag on every release:
Common records get no tag. The owner count is checked first on purpose: a record with thousands of owners isn't rare, even if even more people want it. For example, a release with 40 haves and 160 wants is Rare · In demand, while one with 3,000 haves and 9,000 wants is only In demand.
Connect Discogs and VinylRank tags every release in your collection and wantlist. In Browse, filter by Rarity to list only the rare or in-demand ones — useful for deciding what to insure, what to keep, and which wantlist records to chase first.
